isdn backup
Greetings all, Got a question on routing with ISDN backup. Could someone shed some light on how to properly implement the backup command with routing? I'm using the backup command, and ip unnumber for both primary and backup interfaces. int loop 0 R3 int s0/0-primary--int s2 R5 int loop 0 (5.0.0.5) int di1---backup---int di1 Below is config. What static route can I use to complete the routing to the remote end? Because unnumbered addresses is use, I'm unsure what the static route should look like. The only thing I can think of is using floating static, but that sort of defeat the purpose of the backup command.

ISDN Backup
Hi, I'm having some issues with ISDN backup failover and hopefully someone has done this before. -Central site with a dedicated T1 through serial int. to Remote site router -Central site also has a ISDN to Remote site to a second router The Central serial has the BRI as a backup. Also, we are NOT using RIP (although this is not out of the question) When we pull the T1 the ISDN comes up and everything seems fine. But when the T1 is put back, there are very weird things happening. I'm pretty sure its routing, so I've include the route commands of each router. Any thoughts, ideas, suggestions would be greatly appreciated. Thanks. Chris Central Router 0.0.0.0 0.0.0.0 192.168.2.10 ---This route goes to the internet ip route 192.168.1.0 255.255.255.0 123.123.123.1 -- This goes to the Remote site through the T1 router ip route 192.168.1.0 255.255.255.0 Dialer1 50 -- This goes to Remote site through ISDN router Remote Site T1 Router ip route 0.0.0.0 0.0.0.0 123.123.123.2 - Goes to Central T1 ip route 0.0.0.0 0.0.0.0 192.168.1.2 50 - Goes to Central through Remote ISDN (192.168.1.2 is LAN side of ISDN router) Remote site ISDN Router ip route 0.0.0.0 0.0.0.0 192.168.2.1 - 2.1 is ethernet side of Central router (ipunnumbered over ISDN) Hope this is clear enough. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
ISDN backup
Dear gang: I have the following situation: SiteA---SiteB---SiteC Site A, B, C are interconnected like above. Now I need to deploy ISDN backup. SiteC is a Cisco 3660, Site B, C are Cisco 1750 and have only one BRI interface each. Can I use the ISDN BRI link between SiteA and SiteC to prevent the primary link lost between Site A and Site B, that's mean, if the primary link between site A and siteB lost, the site A will activate the ISDN BRI backup to SiteC, do you think it can be realized? How to? Thanks very much.

Re : ISDN Backup
Hi jenny, Yes, I agree that with floating static routes backup delay command would not work. When my serial link is completely down then the ISDN backup works perfectly well. It is only when the serial link is flapping that the real problem comes up as neither the condition of the link is good enough to handle the load nor does it allow ISDN to takeover. In such situations how can I prevent downtime by allowing the ISDN to take the load. Secondly I wanted to increase the ISDN bandwidth by adding more ISDN lines.( The present bw is 128kbps (multilink enabled) Any hints/suggestions on that would also be appreciated. Thanks & Regards Amit You don't need to use the backup delay command if you're using floating static routes for backup, in fact I'm not sure that it will actually do anything (how does it know what the secondary interface is without a backup interface command?), but I've never actually tried using it with floating statics. Using floating statics, how quickly the backup line kicks in should depend on the convergence time of your routing protocol and design. EIGRP should be pretty quick, generally. What puzzles me, though, is the statement 'isdn backup is not able to activate (momentarily activates and then disconnects)'. Do you mean that the ISDN call doesn't work, or that the call is disconnecting before the idle timer expires or what? Generally (depending on bits of the config that you haven't shown), if the serial link goes down for long enough for the routing table to point to the ISDN instead, the ISDN will call and will stay up for at least 120 seconds (default idle time), even if the routing quickly reconverges back to the serial. If the serial link goes down (or has errors) for such a short period that the routing table does not point to the ISDN, then the ISDN won't call at all. Does it work OK when the serial link goes down and stays down? If so, how quickly does the ISDN activate? If the serial link is flapping, is the ISDN call (including PPP negotiation if you're using PPP) successful? debug isdn q931 and debug ppp neg or debug ppp auth may show any connection problems, and debug dialer may show why it is disconnecting.

Re: isdn backup
What are you trying to backup here? I don't see any routing. Start with a working primary first and I can probably give you suggestions for a solution. Roughly, what you need are two static routes with different weights so the primary is favored, and the backup is much more costlier, or, set the dialer as the default route with a static 0.0.0.0 pointing to the primary, that way, when the primary disappears, the static leaves the table and the dialer goes up. remember to write an access list on the dialer to prevent dialing for RIP updates, etc. depending on what type of traffic you have traversing the router. -Erik - Original Message - From: "Clue Less" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, September 21, 2000 10:25 AM Subject: isdn backup | Greetings all, | | Got a question on routing with ISDN backup.

Re: isdn backup
Hi Erik,
I am just trying this out at this stage. For discussion sake, say I
want to get from r3 to network 2.0.0.0 which is on ethernet of R5:
r3-s0/0--primarys2 r5 ---e1 (2.0.0.0/8)
di1---backup---di1
till using unnumber loop 0 for both primary and backup int.
If static route is to be use, what should it look like?
Your first solution below is using floating static, which I know it
would work. But is there a way to do it without floating static?
Cause if floating static is use, the "backup" command seems
unneccessary.
Not exactly sure what you mean on the second solution, could you
provide sample config?
I got eigrp instead of static route to work earlier, was a bit
surprise to see r3, r5 form neighbor even though they're on different
subnet. r3 (3.0.0.3) & r5 (5.0.0.5). does anyone know if this is
right?
ClueLess.

Re: ISDN Backup
Chris, What are the specific problems you are seeing the T1 comes back up? The only routing issues I would look for would be to make sure you have recursive routing configured wherever you have IP unnumbered configured. Either that, or I would get rid of ip unnumbered alltogether since this is a private network, and there is no risk of running out of IP address space. Does the ISDN router have a recursive host route to the 2.1 address which says it is reachable through the BRI/dialer? I think the easiest/cleanest way to do his would be to run the routing protocol, and have the Remote ISDN router do the dialing when needed. Have the Central router advertise a default route to the Remote T1 router, which would also have the floating default route pointing to the ISDN Router. When the T1 connection is lost, the floating static route is installed, and traffic is directed to the ISDN router which only needs a static default route going out its BRI. Since the remote routers share a LAN segment, you could also look into implementing HSRP where the Remote T1 router is confiured as the active router, and therefore receives all traffic from the LAN users who need to get to the Central site. If that router fails, or if the T1 interface goes down, the ISDN router now becomes the active router and receives the traffic from the LAN users and sends it out the ISDN interface. A combination of floating static routes with a dynamic rouing protocol and HSRP is a good design to go with, since you achive redundancy on layer 1, 2 and 3. Floating statics with a routing protocol ensure the Remote T1 router is notified when, for example, the T1 interface on the central site goes down. In such a case, the T1 interface on the Remote could stay up and floating statics alone would not notify the Remote T1 router of the loss of connection. The dynamic routing protocol will. HSRP allows the ISDN router to be notified when the T1 interface or the ethernet interface on the Remote T1 router goes down, or when the entire router fails. michael a.o >From: "Chris Sees" <[EMAIL PROTECTED]> >Reply-To: "Chris Sees" <[EMAIL PROTECTED]> >To: <[EMAIL PROTECTED]> >Subject: ISDN Backup >Date: Thu, 9 Nov 2000 14:21:21 -0500 > >Hi, >I'm having some issues with ISDN backup failover and hopefully someone has >done this before. > >-Central site with a dedicated T1 through serial int. to Remote site router >-Central site also has a ISDN to Remote site to a second router >The Central serial has the BRI as a backup.

BCRAN: ISDN backup
When using a BRI interface as a backup interface for a serial interface, the BRI interface goes into standby mode and cannot be used for anything else. However, if I make the BRI interface a member of a dialer pool and create two dialer interfaces for that pool to act as logical interfaces for the one BRI interface, I can make the dialer interface 1 the backup interface for the serial interface, and use dialer interface 2 to communicate through my BRI interface while it's not being used as a backup. This is all too cool !!! - Now to the questions: 1) What happens if the WAN on the serial interface goes down and the dialer interface 1 becomes active and then I try to use dialer interface 2? 2) What happens if I am using the dialer interface 2 when the WAN on the serial interface goes down and the dialer interface 1 wants to use the BRI interface? My own guess is that the normal rule for dialer interfaces / dialer pools takes effect regardless of the backup interface usage, so if a physical interface is in use by a dialer interface, the requesting dialer interface will have to wait until the fast-idle timeouts on the active dialer interface.

RE: ISDN backup
Dear gang: I have the following situation: SiteA---SiteB---SiteC Site A, B, C are interconnected like above. Now I need to deploy ISDN backup. SiteC is a Cisco 3660, Site B, C are Cisco 1750 and have only one BRI interface each. Can I use the ISDN BRI link between SiteA and SiteC to prevent the primary link lost between Site A and Site B, that's mean, if the primary link between site A and siteB lost, the site A will activate the ISDN BRI backup to SiteC, do you think it can be realized? How to? Thanks very much.

RE: Re : ISDN Backup
I think you are missing some commands from the config on your router. if you want to back up the interface you have to use the BACKUP INTERFACE command on the primary interface. And to have a threshold level you need to use the command BACKUP DELAY, and for the threshold you need to use the command BACKUP LOAD which will be a percentage of the primary line's available bandwidth that the traffic load must exceed to enable dial backup.

Re: Re : ISDN Backup
You do not have to use the BACKUP INTERFACE command, that is just another way of doing it. I like the floating static commands much better, I can test the ISDN connectivity without having to take the serial interface down. And the Backup Interface command does not work very well in a frame relay situation. I do agree you need to add the commands for Backup Delay, both for going to ISDN and going back to the primary. As for preventing the WWW traffic when on ISDN, apply an access list to the BRI to prevent it.

Re: Re : ISDN Backup
You don't need to use the backup delay command if you're using floating static routes for backup, in fact I'm not sure that it will actually do anything (how does it know what the secondary interface is without a backup interface command?), but I've never actually tried using it with floating statics. Using floating statics, how quickly the backup line kicks in should depend on the convergence time of your routing protocol and design. EIGRP should be pretty quick, generally. What puzzles me, though, is the statement 'isdn backup is not able to activate (momentarily activates and then disconnects)'. Do you mean that the ISDN call doesn't work, or that the call is disconnecting before the idle timer expires or what? Generally (depending on bits of the config that you haven't shown), if the serial link goes down for long enough for the routing table to point to the ISDN instead, the ISDN will call and will stay up for at least 120 seconds (default idle time), even if the routing quickly reconverges back to the serial. If the serial link goes down (or has errors) for such a short period that the routing table does not point to the ISDN, then the ISDN won't call at all. Does it work OK when the serial link goes down and stays down? If so, how quickly does the ISDN activate? If the serial link is flapping, is the ISDN call (including PPP negotiation if you're using PPP) successful? debug isdn q931 and debug ppp neg or debug ppp auth may show any connection problems, and debug dialer may show why it is disconnecting.

ISDN Backup [7:4462]
Just wanted to let the group know of a little trick I came across this weekend. I have an ISDN line that I hooked up to a NT1 with two S/T interfaces. I was able to connect 2 2504's back to back through the telco cloud. Each router pulled one TEI each. This makes it possible to perform dial-backup and other isdn simulations without paying for 2 isdn lines (just can't do multilink) or buying an expensive ISDN sumulator. Just thought I would share because I have never come across this configuration before.

RE: BCRAN: ISDN backup
>From what I understand from the BCRAN course, you are right, the ISDN will not disconnect just because the Serial line went down if you are using it. However, if you configure your logical dialer without load thresholds and ppp multilink you can use 1 B channel for 1 connection so that if you are dialing out one dialer it will use a single b-channel and when the link goes down and it uses the other dialer interface it will use the second b-channel. We do something similiar excpet we use 2 dialer interfaces for backup to use a single BRI. When the PVC's go down one dialer will use 1 b-channel and the other will use the next b-channel on a single BRI. I do not believe you can configure which B-channel to use, just don't configure PPP multilink or dialer load thresholds, and the 2 maps will use the available channel. -Original Message- From: Ole Drews Jensen [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 09, 2000 10:50 AM To: '[EMAIL PROTECTED]' Subject: BCRAN: ISDN backup When using a BRI interface as a backup interface for a serial interface, the BRI interface goes into standby mode and cannot be used for anything else.

If your dlsw peers point to an physical interface that goes away --> dlsw peers will go away . This is the main reason to work with loopbacks . DLSw only requires that the peers are reachable . For the backup , all routing stuff should be inplace before 3 DLSw keep-alives . ( 90 seconds ) How you handle that has nothing to do with DLSw .

ISDN backup for increased bandwidth
We have a site with a quirky FRelay burst pattern. Although they burst very rarely, the uers seem to all be all too aware of the times when it is happening. Our usage numbers dont justify bumping up their CIR so I've been investigating alternatives. I was wondering if anyone out there uses ISDN backup to provide more bandwith when the FRelay circuits get saturated. This seems like it might be a good solution since it could help out during episodes of bursting. But is it practical financially? How much more expensive if an ISDN connection than a Frame Relayat 128k CIR? This particular site would be calling from Boston to Santa Clara. Any insights, comments, etc are greatly appreciated. If I get enough responses, I'll post a summary. **NOTE: New CCNA/CCDA List has been formed.

Re: ISDN Backup [7:4462]
Yes, its worthwhile. Alot of people find that paying for an NT1 and an ISDN line is cheaper than the simulator. But with the simulator you can do dial-backup, BOD, multilink, etc. Brian On Mon, 14 May 2001, Ambern, Jeff wrote: > Just wanted to let the group know of a little trick I came across this > weekend. > I have an ISDN line that I hooked up to a NT1 with two S/T interfaces.

Lets say that if both ptp links drop, you want site A to call site B. Presumably site A can usually see routes to various site B addresses via EIGRP (maybe even nicely summarised). On site A, set up a static route to a site B address (or to a summary - whatever matches your EIGRP routes), with an administrative distance of say 200, pointing to the dialer interface for the BRI (if you're using a dialer - or straight to the BRI). Then, if one ptp link drops, site A will still use the EIGRP route across the other ptp link. If both ptp links drop, the static route will kick in and send traffic via the ISDN.

Re: ISDN Backup for ISDN BRI
If that is what you want to do which is not very effiecent, but...all you need to do is add another dialer string to the interface and then it will try the first dial string and then the next one and then next one and so on. - Original Message - From: "Radford Dion" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, August 21, 2000 1:10 PM Subject: ISDN Backup for ISDN BRI > Hi everyone. > > Is there any way to backup a DDR ISDN line with the same ISDN line?

RE: isdn backup query [7:70443]
Considering that your default route is probably pointing to a next-hop of the other side of the serial or perhaps is pointing to the serial interface itself, you would still need to tell the router to send traffic out of the BRI0 in the event that your serial goes down. If you serial interface goes down, it will take your current default route out of the routing table as well. So what you need to do is create a "floating" default static route which is nothing more than a default route with a higher preference so that it will only become active when the default route pointing to the serial is removed.

Re: ISDN backup problem [7:19894]
Alvin, If I'm not mistaken you BRI circuits should have two(2) channels. Why not simply set R1 to dial the core on the 1st channel and R2 on the 2nd. Of course you would have to change the configuration on your core router for to support Dialer Profiles so you could receive both calls simultaneously If made the config additions you'll need below. I don't know what routing protocol you're using if any so I'd suggest using floating statics so as long as the primary path is down the ISDN circuit will be the default path out of the network. If there's a dynamic routing protocol(I'm thinking based on the "broadcast" keyword in the BRI config) already running between the "core" router and R1 and R2, I'm assuming the ISDN isn't configured based on you're use of the "backup interface" command. Anyway, just some thoughts and things to consider... NOTE: *** You could look at creating a loopback interface on the core router and using the "ip unnumbered loopback" command under the dialer profiles for each connection this way you maintain the existing IP scheme. The configs for R1 and R2 should stay pretty much the same except R1 will use the # for BRI line 1 on the CORE router and R2 will use the 2nd..

routing issue with ISDN backup [7:13045]
Hello everyone: I have some routing issue here. I have central office with a core router sitting behind the PIX. All branch office (remote) routers connect to central router using frame relay & ISDN as back up. Each branch office (having 1 Serial, 1 ISDN, 1 Eth Int) should be able get to any other branch office & to Internet through PIX. All IPs used will be private & PIX will be doing NAT. I am planning on having EIGRP to route between all routers over frame relay & floating static route to trigger ISDN if FR goes down. This floating static route will be something like ip route 0.0.0.0 0.0.0.0 10.0.0.1 200 (10.0.0.1 will be IP of central router) In each branch office router EIGRP will have Ethernet & serial networks in it. This will make all internal routing fine when the network is on FR. But how do I route Internet traffic to core router so that it can send to PIX? I am already using default static route to core router, which I want to be used only when FR is down. Is there any way in EIGRP to propagate default route through network from core router?

Re: Frame with ISDN Backup [7:56449]
Hmm...I just noticed something about what Paul is asking. He said he has a _frame relay switch_ that he wants to use ISDN as a backup. Paul, are you asking how to tunnel frame relay over ISDN? I believe this can be done but I don't recall the configuration. I remember at one time I had a configuration that allowed a frame PVC to be tunneled over an async port to allow one more port on my frame switch, but unfortunately I don't recall the details. I believe there is also a Cisco IOS feature that has something to do with frame relay over ISDN but I've never researched it. Is this what you're trying to accomplish?

Re: Frame with ISDN Backup [7:56449]
Thanks for all your input guy's I think I confused the issue somewhat !! What I meant was that 'the 7200 is terminating frame relay circuits and not acting as a switch' !! (Thanks MADMAN), and that if the Frame fails the ISDN would immediately kick in to provide connectivity Anways ... I've got enough info from you all to start reading up ... Thankx again ...

Why ISDN backup line come up ? [7:12920]
Hello all. I have 2 routers connected using leased line.Now I am trying to put a ISDN backup ,but the backup line does not come up. The status of ISDN line when the serial int. is up ,is BRI2/2 is standby mode, line protocol is down and should change to up upon going the serial line down but it's status remain unchanged even the serial link goes down . I have configued the serial int with backup interface BRI2/2 backup delay 5 10 commands . Also i tried to simulate the situation by putting the modem at Router A off to trigger the backup ISDN call but it does not happen and the ISDN status remain in standyby mode only. Can anybody help whether anyadditional command needs to be put up in either Serial or Bri interfaces? I am giving here th configuration of both the routers, routerA# interface BRI2/2 description "Backup connectivity " ip address 172.16.128.49 255.255.255.252 no ip directed-broadcast encapsulation ppp dialer map ip 172.16.128.50 name routerB x dialer-group 2 isdn switch-type basic-net3 interface Serial1/3 description "Leased link to RouterB" bandwidth 128 backup delay 5 10 backup interface BRI2/2 ip address 172.16.128.17 255.255.255.252 no ip directed-broadcast no ip route-cache no ip mroute-cache RouterB# interface BRI1/2 description "Backup connectivity for RouterA ip address 172.16.128.50 255.255.255.252 encapsulation ppp no logging event subif-link-status dialer idle-timeout 3000 dialer wait-for-carrier-time 60 dialer map ip 172.16.128.49 name routerB YYY dialer-group 1 no fair-queue interface Serial0/0 ip address 172.16.128.18 255.255.255.252 logging event subif-link-status bandwidth 128 hold-queue 75 in Thanks in advance for help Regards Bware Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=12920&t=12920 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

What are the results of show int bri0 and show isdn status? That might alert you to the problem. If you've posted the entire config then you definitely are missing at least one very important thing.

By the way, you really didn't give us any indication of what you saw as the output from the router - I'll just assume that you saw nothing. 1. From the configuration, it is not obvious what kind of ISDN switch you're using. Do you know if you need to add a statement to define the switch type? (I'd guess yes, unless the rules changed in 12.2) 2. Someone else indicated that you need to check the ISDN status using the appropriate show command. You'll learn something from doing that check. Mostly, you'll learn how to read the status of the ISDN circuit, and what the different fields indicate on the results of the show isdn status command. Learning the debug commands (debug isdn q921, debug isdn q931) are also valuable tools. Learn to use them to diagnose a problem. 3. Look at the purpose of the dialer map statement. Someone else indicated that you need to configure a destination phone number for that. I agree with that indication. Paris doesn't know what number to dial to reach New_York_City. 4. Someone suggested using backup-interface. I'd counsel you NOT to go down that road until you have the point-to-point ISDN configuration stable and it's coming up when you want it to. 5. Another person suggested that you add an administrative distance to your static route. That would be a good idea. When you do that, your ISDN circuit will come up only when the route for the serial link goes away (assuming that it's the only route to the other router) 6. Some switches prefer/require that you suffix the dialing numbers to the SPID assignments. Learn which switches need that kind of input. 7. What other resources have you used to learn configuration of ISDN? There are different layers of ISDN configuration. They are, in order of bottom to top: a. the ISDN physical connection itself (S/T interfaces require NT-1's or a simulator that has an S/T interface, U interfaces have a built-in NT-1) Cisco 2500 series routers (except the 2524/2525) have an S/T interface. The 2524/2525 has two flavors of modular BRI, S/T or U. Cisco 4000 series NP-4B and NP-8B have S/T interfaces. I'm not sure about the 26/3600 series, but I'm sure someone else on the list does know and might be willing to share that info. b. ISDN interface establishing communication with the ISDN switch (q921 signalling - requires the correct ISDN switch type configured and the proper physical connection) c. ISDN interface obtaining TEI (q931 signalling-requires the ISDN SPIDs configured properly) d. triggering the interface to dial (either IP or backup-interface or snapshot routing, requires the dialer-map and dialer-lists configured properly) e. encapsulation negotiation (ppp-requires both routers have a common encapsulation) f. authentication (chap-requires username/passwords used in the dialer-map statements match on both routers) g. IP routing (static or dynamic routes) over the interface (requires routing protocol including static to route to the correct destinations via the BRI interfaces). h. establishing multilink (requires the dialer-load statement) 8. Extraneous commands in a BRI configuration sometimes spell disaster, so take out anything that you don't absolutely need from a basic's perspective. Otherwise, your configuration is a good start. Unfortuately, incomplete BRI configurations don't work, and don't give you any indication of why they don't work. I'll refer you to a very valuable resource, which I still use when I get stuck on an ISDN configuration. It's Cisco's TAC page for ISDN Technology: http://www.cisco.com/pcgi-bin/Support/PSP/psp_view.pl?p=Internetworking:ISDN (watch the URL wrap) Here's a page with a very basic configuration that you can learn from, step by step: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/dial ts_c/dtsprt3/dcdbri.htm (watch the URL wrap) ISDN is a very complex configuration until you've mastered the basics, which means understanding the different layers of BRI configuration. I'd suggest that you study these pages, and then if it still doesn't work, c'mon back and post the configurations from both routers and the results of some of the show commands that you'll learn from reading the basic's pages. Good luck in your studies, and let us know what you learn about ISDN. -e- - Original Message - From: "nettable_walker" To: Sent: Friday, November 02, 2001 5:27 PM Subject: ISDN backup will not activate [7:25129] > 11/2/2001 4:30pm Friday > > Professional's, I would like to get traffic from Paris to use ISDN when the > primary link goes done. > When the serial link goes down the ISDN never comes up.

Delay on ISDN Backup with Dialer Profiles !?!? [7:49441]
Hi all, How can I configure a delay with dialer Profiles ?? Let's say I have a the following scenario with three routers (FR with OSPF). In case of the failure of the connection between router_3 and router_1 , either router_2 or router_3 can bring up an ISDN line. First it should come up the line between R1 and R3, but if after let's say 90sec the ISDN isn't up, router_2 should connect to router_3 via ISDN. So, how can I configure delay under "int DialerXX" ?? In every case router_3 should be the Called Router, and the others the calling routers ... router_2 * router_3 ** * * ** router_1 * on router_2 interface Dialer0 description ** ISDN Backup to router_3 ** ip address x.x.x.6 255.255.255.252 encapsulation ppp dialer remote-name router_3 dialer idle-timeout 300 dialer string 123456 dialer-group 1 - on router_1 interface Dialer0 description ** ISDN Backup to router_3 ** ip address z.z.z.2 255.255.255.252 encapsulation ppp dialer remote-name router_3 dialer idle-timeout 300 dialer string 123456 dialer-group 1 - on router_3 interface BRI0 description ** ISDN Backup to router_1/router_2 ** no ip address encapsulation ppp dialer pool-member 1 dialer pool-member 2 isdn switch-type basic-net3 ppp authentication chap interface Dialer0 description ** ISDN Backup to router_1 ** ip address z.z.z.3 255.255.255.252 encapsulation ppp dialer idle-timeout 300 dialer pool 1 dialer map ip z.z.z.2 name router_1 broadcast dialer-group 1 ppp authentication chap interface Dialer1 description ** ISDN Backup to router_2 ** ip address x.x.x.7 255.255.255.252 encapsulation ppp dialer idle-timeout 300 dialer pool 2 dialer map ip x.x.x.6 name router_2 broadcast dialer-group 1 ppp authentication chap dialer list 1 . bla bla any ideas ?? cheers, monti Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=49441&t=49441 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Subject: Why ISDN backup line come up ? [7:12920]
Comments within and below. First, I noted that you used the backup interface command on a physical interface. Have you considered the idea of using dialer interfaces as the backup interface? When you do this, it offers you a little bit more flexibility. For example, I noted that your serial interface is a 128kbps link. You may want to explore the possibility of using a dialer interface for two purposes. One purpose would be to act as a backup interface. Another purpose could be to use it for additional bandwidth if your primary serial interface gets congested. > Hello all. > I have 2 routers connected using leased line.Now I am trying to put a > ISDN > backup ,but the backup line does not come up. > The status of ISDN line when the serial int. is up ,is > BRI2/2 is standby mode, line protocol is down > and should change to up upon going the serial line down but it's status > remain unchanged even the serial link goes down . You are correct. The issue is one of troubleshooting. Assuming you have a primary link filure, your backup interface should go active (up and up) after a 5 second delay that you configured. According to you this is not happening. You have not mentioned what troubleshooting steps you have taken. When you remove the backup interface command from the primary interface, what is the output from "show isdn status"? Are layers 1 and 2 good? Assuming they are good, when you place the backup interface command back on the primary interface, what happens when you do a "debug dialer and a debug ppp neg" after the primary link has been made to fail. Assuming you had a "dialer-list 1 protocol ip permit" statement near the end of your config [note- you didn't post your entire config, so I am guessing here] you should get a call placed to the other side.

One of the many/several options for ppp is authentication. You indicated in your dialer map statement that you will be doing authentication by use of the "name" command. Unfortunately however, you have not specified what method is to be used on either end of the link. I would start with "ppp auth chap". It ends to be more secure. > interface Serial1/3 > description "Leased link to RouterB" > bandwidth 128 > backup delay 5 10 > backup interface BRI2/2 > ip address 172.16.128.17 255.255.255.252 > no ip directed-broadcast > no ip route-cache > no ip mroute-cache How are you actually testing this? Since you didn't supply a full config, this is not readily apparent. For example, is there a LAN on the other side of router B? If so, what is the network address of the LAN interface? Where is the static (or other) route that points to this network? When you test your reachability, do you ping the other side of the WAN link, or the other side of the LAN network on router B? > RouterB# > interface BRI1/2 > description "Backup connectivity for RouterA > ip address 172.16.128.50 255.255.255.252 > encapsulation ppp > no logging event subif-link-status > dialer idle-timeout 3000 > dialer wait-for-carrier-time 60 > dialer map ip 172.16.128.49 name routerB YYY > dialer-group 1 > no fair-queue Here there is an additional problem. Look at the name command two lines above. The host name following the name command should be the target you are trying to authenticate, not yourself. Also, since you didn't post your entire config, I have no way of knowing whether you set the username/password lists for both routers. They would look like this and appear in the global config near the top: user RouterA pass sameone user RouterB pass sameone Note the passwords are the same, also referred to as a "shared secret". > > interface Serial0/0 > ip address 172.16.128.18 255.255.255.252 > logging event subif-link-status > bandwidth 128 > > hold-queue 75 in > > > Thanks in advance for help > Regards > >
Re: Subject: Why ISDN backup line come up ? [7:12920]
I ran into a similar problem. In my case, the issue was that I needed to add a route that the ISDN interface was performing backup for, give it a higher admin distance, so that it wouldn't bring up the backup interface unless the primary route failed, and assign it to the interface. Hope that helps.

I went ahead and took your existing configs and preserved as much as I could from them. I added the functionality of dialer profiles to the config. This gave three direct benefits. First, your ISDN interface will no longer be in a down status because it is a named standby interface. Second, it allows you to use the ISDN interface to possibly back up a second serial line should you install one later.

Re: is there anyone migrating isdn backup to dsl b [7:58568]
It sounds like DSL has a low mean time between failure (MTBF) but a high mean time to repair (MTTR), which can be just as bad, especially if it's your only backup. Of course, your mileage may vary (YMMV), depending on the service provider. Also, a service level agreement (SLA) would help, as Chuck mentions.

Re: is there anyone migrating isdn backup to dsl b [7:58568]
A benefit to DSL as backup is that you should immediately known when it goes down. This allows you to have the telco begin repairs while your primary circuit is functioning. With ISDN, if you don't use it very often there may be a problem with the line and/or equipment and you'd have no idea until the primary failed. As far as I'm concerned, I'd rather not wait until my primary fails before I discover that my backup also is not functioning. This has happened a couple of times in the last year with ISDN and it's a little frustrating. So far, I haven't had an instance where a primary frame relay circuit was down at the same time as a DSL backup circuit except for when Backhoe Bob has attacked one of our locations and dug up the lines. In that case, ISDN would have failed as well so it's no big deal.

Re: is there anyone migrating isdn backup to dsl b [7:58568]
I say DSL has no "multi-service" (or very limited) capabilities. There isn't much in terms of QoS, LFI or other voice/video tools. Plus there is no QoS across the DSL network (if over Internet) and no standard nation-wide (no National provider). If you say, there is no voice going across network, or video, then you are doing your client a dis-service by providing no upgrade path towards that eventual path.

RE: is there anyone migrating isdn backup to dsl backup [7:58598]
I would second Chuck on this. I have seen some folk with DSL backup when the backup didn't work. Always was something with the provider. If you go this route, make sure to test/use the DSL connection on a weekly or bi-weekly basis. Same could be said for ISDN though.

RE: is there anyone migrating isdn backup to dsl backup [7:58622]
In our case our DSL lines all terminate on an ATM T1 on one of our routers. I've configured OAM to test the lines and to declare the line down when OAM cells are not returned. With this I immediately know when a DSL line is down and can take action to correct it. This brings up another key point. Sure, we're using DSL, but it's not going to the public internet. We have a private line service in which the provider multiplexes our DSL circuits onto the aforementioned ATM circuit. This alleviates the concerns some people have about running private data over public networks. John >>> "Erick B." 12/4/02 9:33:35 PM >>> I would second Chuck on this.

Re: is there anyone migrating isdn backup to dsl backup [7:58987]
I did this for a client against my better judgement and wrote it up as such. DSL around here has not been stable enough and I've had a few cases where the telco disconnected the DSL line without saying anything. When asked about it, they replied they had not seen any traffic and *assumed* it was a dead line. And yes, they have had 3 failures of the DSL so far in the last 6 months. Twice when they actually needed it.. once during testing. Some of this is from the DSL company changing hands several times in the last year.

Use something like whatsup gold to monitor the DSL line. Have it send traffic across the line every 60 seconds or so. We're doing like that with our cable-modem backup connection and it's great! It does two things: 1) puts occasional traffic across the line so the ISP doesnt think the line is not in use, and 2) let's me know when the lines goes down and I have to call my ISP! thanks, -Brad Ellis CCIE#5796 (R&S / Security) Network Learning Inc [EMAIL PROTECTED] www.optsys.net (Cisco hardware) Voice: 702-968-5100 FAX: 702-968-5104 ""MikeS"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > I did this for a client against my better judgement and wrote it up as such. > DSL around here has not been stable enough and I've had a few cases where > the telco disconnected the DSL line without saying anything.

kewl idea, theres always the option of paying a little more for a biznis dsl link, so that if it goes down they know about it. That plus your own monitoring is what I'd do.

Re: Any idea how to configure ISDN backup with day time [7:29654]
I don't know if this will work, but perhaps you could try configuring a time-based access list and then use that in your dialer list statement. This should allow you to make certain packets interesting during specific times.

Re: Any idea how to configure ISDN backup with day time [7:29656]
If this link presumably is not used off hours then there will be no "interesting" traffic to trigger the line hence it will not come up at night.

Use a time based access list as the dialer-list. dialer-list 1 protocol ip list 100 ! access-list 100 permit ip any any time-range dial-backup ! time-range dial-backup periodic weekdays 08:00 to 17:00 HTH, -Michael Cohen -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Sebastien Venturoso Sent: Wednesday, December 19, 2001 11:15 AM To: [EMAIL PROTECTED] Subject: Any idea how to configure ISDN backup with day time restriction [7:29646] Hi, I looking to configure ISDN to backup a leased line, but I don't want to use the ISDN backup if the main line goes down during the night.

Re: Any idea how to configure ISDN backup with day time [7:29668]
Looks like the link in my original post got stripped out. Oops! http://www.cisco.com/warp/public/793/access_dial/10.html You can restrict the interesting traffic to specific time(s) of the day with the time-range command. The above link explains it pretty clearly. In case the url gets stripped out again, go to CCO and do a search on time based acl. It's the first page that comes up in the results.

RE: ISDN backup - Time based access lists or backup interface - h elp needed
Hi there I have had a the same problem with a client of mine and got advice from this group on time based access lists . They work well , just make sure your NTP (Network Time Protocol) is correctly set up because that can really stuff you around . http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120 t/120t1/timerang.htm Check out this link . It ought to sort you out ! Thanks to those who have passed this knowledge on to me so I can pass it on !!

Memo: Re: Any idea how to configure ISDN backup with day time [7:29655]
You can use time based access lists.First you create time range and use it in access list. but your ios must support ,version 120-7_T does.
