Frame Relay Problem
Hi All, I hope someone can shed some light on the problem I have come across in the following scenario : Three routers, R1,R2 and R3 all connected via a Frame Relay cloud with a router in the middle doing frame relay switching. The frame switch is _not_ fully meshed. R1 is acting as the hub with R2 and R3 being spokes off R1. Hence there is a PVC betweenR1 and R2 and a PVC between R1 and R3. There is _no_ PVC between R2 and R3. The particular lab exercise here specifies that each router much be able to ping every other router in the frame cloud. BUT the use of the 'frame-relay map' command is forbidden, and only R1 can be configured using a subinterface. As I have it configured R1 can ping both R2 and R3 as expected. However, both R2 and R3 can only ping R1 (the hub) yet cannot ping each other. The question stipulates you should use routing and not Layer2 to Layer3 mapping. A debug on the ping from R2 to R3 shows that there is no map entry for R3 hence encapsulation failed. A look at 'sh frame map' shows there is only 1 entry and it is for R1. This sh frame map is identical on R2 and R3. So the question is, how can I get R2 and R3 to be able to ping each other using routing and not the frame relay map command. It's got two of us here studying for our CCIE stumped, so im hoping someone out there has an idea as to how this can be accomplished. Also, as this is for the CCIE, static routes are not an option. Cheers. Jim. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Frame Relay problem
Your telco provisioned the PVC on the same circuit as DLCI 17, this is evident by the show frame-relay pvc command. You have it configured on Serial 0, which is why it shows up, down. But it is actually on Serial 1. Try configuring the sub-interface on Serial 1, and I bet it comes up and starts running. -j Subject: Frame Relay - Real Life Problem Date: 30 Nov 2000 00:16:34 -0500 From: [EMAIL PROTECTED] (Adele Galus) Organization: GroupStudy.com Discussion Groups Newsgroups: groupstudy.cisco This is a configuration problem.

Frame relay problem
Hi, Could anyone help with the following : Part of our network consists of Cisco 4500 routers connected via BT frame relay links. The problem I am seeing on all 10 routers is links going down then up, often for exactly one minute : eg .Oct 24 16:25:32 UTC: %FR-5-DLCICHANGE: Interface Serial2/0 - DLCI 592 state cha nged to INACTIVE .Oct 24 16:25:32 UTC: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial2/0. 4, changed state to down .Oct 24 16:26:32 UTC: %FR-5-DLCICHANGE: Interface Serial2/0 - DLCI 592 state cha nged to ACTIVE .Oct 24 16:26:32 UTC: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial2/0. 4, changed state to up The PTT have tested all lines and insist they are clean This is happening about 5 - 10 times a day. The IOS was upgraded not too long ago I think. It is now 12.0(4) This doesn't seem to have much impact but my customer just wants to know why!

FRAME RELAY PROBLEM
I have got a problem with FR Config Running OSPF. Router A & B are connected to C & D over FR PVC but they don't have to talk to each ther. It means A connected to C & D and B is also connected to C & D. I am using FR Subinterfaces with pt-to-pt. What is happening that sometime I am able to ping to router C & router D subinterfaces from router A but sometimes i don't get any response. I am even unable to ping sub-intf of Routers from within the routers. See sample config of one of the routers that i have: interface Serial0 no ip address ip directed-broadcast encapsulation frame-relay ip ospf network broadcast no ip mroute-cache ! interface Serial0.1 point-to-point ip address 131.18.19.185 255.255.255.252 ip directed-broadcast ip ospf network broadcast frame-relay interface-dlci 310 ! interface Serial0.2 point-to-point ip address 131.18.19.189 255.255.255.252 ip directed-broadcast ip ospf network broadcast frame-relay interface-dlci 210 This is config of router B connected to C & D and subintf of C &D are on same subnet as subintf 0.1 and 0.2 on this router. Is pt-to-pt with sub-intf OK for this scenario? Any suggestions... What is the possible cause of problem?? Why I am even unable to ping local subintface from within the router??

Frame Relay Problem
I've set up a frame relay switch at home trying to complete one of the "CCIE Lab all in one" Labs. For my question, what could cause a PVC to be inactive? Things I've checked. Serial is up line protocol is up on both sides. LMI type is the same Clocking is set on DCE side. Encapsulation is Frame relay What else is there to check? All suggestions appreciated.
Re: Frame Relay Problem
If you could post the configs it would help, but here's some ideas to try. Are you sure have inverse ARP working? Have you tried a static route to R3 (from R2) gatewayed to R1's IP and the same on R3 to R2 via R1's IP? Look into Proxy ARP. Just a thought, I've never tried this but, is there a way to make a static ARP entry?

Re: Frame Relay Problem
Unless I'm mis-reading you here this is the correct behavior for a partial mesh. Unless you provide a full mesh you won't get dynamic mappings for both spokes. Also, I assume the PVC from R1 to R2 is one subnet and the PVC from R1 to R3 is another subnet--Frame relay and Inverse ARP alone can't route between them. So if you can't get a PVC between R2 and R3...then run any routing protocol on all 3 routers and you should be able to ping from R2 to R3 and vice-versa (RIP will work fine to prove this point.)

Re: Frame Relay Problem
Sounds like all you need to get your branch traffic to the next hop (hub router) where the hub router will route it for you because it knows of the routes to all destinations. You could use static routes or route maps with the next-hop parameter to do this. - Original Message - From: James Wilson <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Sunday, November 26, 2000 5:50 PM Subject: Frame Relay Problem > Hi All, > > I hope someone can shed some light on the problem I have come across in the > following scenario : > > Three routers, R1,R2 and R3 all connected via a Frame Relay cloud with a > router in the middle doing frame relay switching.

Re: Frame Relay Problem
Nope, all one subnet. i.e all interfaces are on the 10.1.X.X/16 subnet Hence the problem. Im well aware this is the normal partial mesh behavior and that its quiet easily rectified using map statements... but for this particular setup it requests the use of routing and not frame relay map statements.

All interfaces on the frame relay network are in the same 10.1.x.x/16 subnet.

RE: Frame Relay Problem
Then try using policy routing to set the next-hop for all packets to go to the hub which has a route to the other spoke. Then the other spoke should have the same type of route-map. Using this method you won't need to change the routing table, but change the packets themselves. Don't forget that if you are doing this from a local ping on the router you will need to enable the route-map with the local policy command. Regards, Aaron K.

Re: Frame Relay Problem
Ah...now I need more info. Below you stated "only R1 can be configured using a subinterface"--so that's my first question: Is it configured with sub-int's, one for ea PVC? If yes, and they are configured as point-to-point then I believe that each separate PVC is required to be on a separate subnet since the router treats each as a separate interface. In this scenario my original response will work. If no, then are you using one multipoint subint on R1 the Hub router? If so, one subnet works for all three interfaces but I believe you'll need map statements at the spokes. I understand this isn't an option. So please provide more details... If your lab exercise doesn't explicitly disallow point-to-point subinterfaces at the hub router, R1, then I'd configure it that way, with 2 differnet subnets and run RIP on all 3 routers...it will work. If I missed another restriction you're facing please advise soonest...I'm now very interested in this one.

RE: Frame Relay Problem
Title: RE: Frame Relay Problem Maybe I'm missing something, but in looking at your config and cross-referencing the rules of the lab, I can't understand why you didn't just create two subinterfaces on R1. -Original Message- From: James Wilson [mailto:[EMAIL PROTECTED]] Sent: Sunday, November 26, 2000 5:50 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Frame Relay Problem Hi All, I hope someone can shed some light on the problem I have come across in the following scenario : Three routers, R1,R2 and R3 all connected via a Frame Relay cloud with a router in the middle doing frame relay switching. The frame switch is _not_ fully meshed. R1 is acting as the hub with R2 and R3 being spokes off R1. Hence there is a PVC betweenR1 and R2 and a PVC between R1 and R3. There is _no_ PVC between R2 and R3. The particular lab exercise here specifies that each router much be able to ping every other router in the frame cloud. BUT the use of the 'frame-relay map' command is forbidden, and only R1 can be configured using a subinterface. As I have it configured R1 can ping both R2 and R3 as expected. However, both R2 and R3 can only ping R1 (the hub) yet cannot ping each other. The question stipulates you should use routing and not Layer2 to Layer3 mapping. A debug on the ping from R2 to R3 shows that there is no map entry for R3 hence encapsulation failed. A look at 'sh frame map' shows there is only 1 entry and it is for R1. This sh frame map is identical on R2 and R3. So the question is, how can I get R2 and R3 to be able to ping each other using routing and not the frame relay map command. It's got two of us here studying for our CCIE stumped, so im hoping someone out there has an idea as to how this can be accomplished. Also, as this is for the CCIE, static routes are not an option.

Re: Frame Relay Problem
Your suggestions are good, unfortunately i have already tried most of them and other break the rules of the lab Here's a run down : - R1 is currently configured with 1 multipoint subinterface with multiple frame-relay interface-dlci commands. - The rules state only 1 subinterface can be used, and also state only the one 10.1.0.0/16 subnet can be used so that rules out the multiple subnets. - The lab stipulates the ip addresses for R1, R2 and R2 be 10.1.1.1/16, 10.1.1.2/16, 10.1.1.3/16 respectively. So there goes the multiple point to point interfaces / multiple subnets idea. bummer. As you said, Map statements are not to be used. The direct quote from the lab is "Also, one of the problems in this lab [i.e r2 not being able to ping r3] can be solved with multiple frame map ip statements, but this is not the solution i want you to use.

RE: Frame Relay problem
Title: RE: Frame Relay problem Hmm...well, you don't give us a config or show version so we don't know for sure what the LMI settings are or what the IOS version is. However, by the show interface you provided, it looks as if LMI is to blame. Newer IOS autosenses the LMI type, but still, I don't trust it. If you have an older IOS or you have a newer IOS that is "autosensing", I would hard code the LMI type. Also, since IOS sets the LMI type to Cisco by default, when/if you hard code it, you might try setting to use ANSI LMI. Good luck!

RE: Frame relay problem
FR ckts. can drop generally either due to provider switch problem or due to line problem. If you got a CSU/FRAD, check the line performance parameters. First look for stats. to see any errors, specially SES/BES or UAS. Some CSU/DSU provides also status on the errors like Yellow/Red alarm etc. Also check Frame relay parameters like Frame reliability errors and lmi disconnects to isolate whether this is a frame relay issue. From a practical point of view, run a continious ping with 1500 bytes to see whether packets drops but your problem more seem to be a LEC issue or FR switch. Once a ckt. drops it takes exactly 1 minute for FR ckt. to come back up. Hope this helps.

Re: Frame relay problem
This sounds like your router misses LMI status messages every once and a while. This could mean a timer problem or the serial interface could be too busy to process them correctly. My guess is the timer problem, check with the carrier (or use a WAN sniffer) to see how often LMI status messages are being sent from the frame switch to your router, then make sure the defaults or the config on your router matches.

Re: Frame relay problem
You can do 'show frame lmi' on your router and compare 'Num Status Enq. Sent' with 'Num Status Enq. Rcvd'. They should be the same. If they don't match, clear your counters and check again, and check after your problem occurs. Another useful command to check lmi is 'debug frame lmi'. This is a fairly safe debug, unless you have squillions of PVCs. Having said that, don't blame me if turning it on makes your network fall over :-) You can check how often you receive lmi from the switch (make sure it matches your keepalive, which is 10 seconds by default), and every minute (this might vary depending on switch type, dunno) you should see a list of PVCs known by the switch and their status (0x0 is inactive, 0x2 is active if I recall correctly). Having said that, I suspect it's not an LMI problem. If the LMI wasn't received at all, I *think* you would see the PVC showing up as deleted (the switch doesn't know about it), not inactive (the switch knows about it and knows it's down). Do PVCs on all ten routers go down at the same time? If so, I'd seriously yell at your telco.

Re: FRAME RELAY PROBLEM
It is my understanding that on point-to-point interfaces they need to be on seperate subnets. If you have multiple routers coming into one interface, declare the interface a point-to-multipoint interface. Do this when you create the subinterface or use the "ip ospf network X" interface command. See this URL for Design suggestions. http://www.cisco.com/warp/public/104/3.html William Swedberg CCNP CCDP --- Peter Gray <[EMAIL PROTECTED]> wrote: > I have got a problem with FR Config Running OSPF. > Router A & B are connected > to C & D over FR PVC but they don't have to talk to > each ther.

Frame Relay Problem [7:4435]
Hey, I have read through the archives and found information close to what I am needing, but not exactly. Here is the question... I have (3) 3600 series routers connected by Frame-relay links. router#1 is the main, router#2 and router#3 hang off of the main in a hub and spoke config. I have a DHCP server behind router#1 that all subnets use for address's. I am running EIGRP. Router#2 and router#3 have "ip helper-address" statements for the DHCP server. Router#2 can ping the DHCP server and its own serial interface and get DHCP addresses, but router#3 can't ping the DHCP server or its own serial interface, or get DHCP address's. Traffic passes fine, LMI is correct, and PVC's are setup correctly. Both Router#2 and Router#3 have the exact same config(beside network numbers, ip address's, and DLCI's). What would cause a router not to be able to ping it own serial interface??? "show ip int s0" says (up,up) and LMI are increasing every 10 seconds.. Please helpcisco TAC can't even solve this one... I am not a member of groupstudy (yet), so please respond to "[EMAIL PROTECTED]" Thank you guys!!

frame-relay problem [7:60522]
I've got 2 frame-relay PVC's to 2 different remote locations... Both identical locations with same amount of PC's running same applications... Greenbay and Madison and the central location is Milwaukee. When doing a normal ping test to Greenbay and Madison the Greenbay locations response times are almost 3 times faster. When doing a large 4048byte ping test the Madison locations response times are a little bit faster.. The routers are 2500's and the speed of both circuits is 128k port 64k CIR frame-relay. Weighted fair queueing as is the default. Why would my ping times be 3 times faster to Greenbay with normal ping and a little faster to Madison with a large ping? Of course SBC hasn't found anything wrong. Any advice would be helpful, this one is stumping me.

RE: Frame Relay Problem -- SOLUTION CONFIGs
I'm glad that you resolved the problem. Policy routing can be a very powerful tool and it overrides limitations of not being able to use static routes. You should take the time to review all of the possibilities availble with policy routing. Of course, don't forget that if you want to policy route locally generated traffic use the ip local policy command. That will get you everytime otherwise. Regards, Aaron K.

Re: Frame Relay Problem [7:4435]
R, Are you using inverse arp or maps statements for your dlci to ip mappings? If you are using mappings you will need to configure a map statement as the one to the hub but map it to the local ip of the router. Use caution if on production network.

Re: Frame Relay Problem [7:4435]
Make sure you have 'ip bootp server' configured (default), and not 'no ip bootp server'. It will stop the ip helper-address from forwarding DHCP requests if you have it disabled. Use extended ping to ping from the LAN side of the router that is at the site with DHCP problems. 'term mon' and 'debug ip dhcp server events' and 'debug ip dhcp server events' (I think those are the right debugs, I can't seem to find any for ip helper-address or bootp debug commands so I'm guessing that is it. Actually I think the 'debug ip dhcp server *' stuff is for the local dhcp server that could be configured on the router. You'll want 'debug ip udp' but be aware that this will potentially generate a ton of debugs depending on normal traffic. I just did it on my local VoIP network: Bad idea, hehee. What's the fastest command to kill all debug on a router?

RE: Frame-Relay Problem [7:41250]
Do you have another router to connect to the 3660? This would give you a better idea of how it really works. It looks like right now you are trying to do frame relay back to back, which also works, but it depends on how you have your settings.

Check the clock rate and cabling on both ends. If the clock rate specified is different than what the module supports, then I believe the line will come up and go back down.

Re: Frame-Relay Problem [7:41250]
Sean brings up a good point to check the maximum clock rate of your module. I've seen more than 1 person try to use the A/S module for 1.544Mbps However, the A/S module that he refers to supports a max of 115.2Kbps in async mode and when put into sync mode supports a max of 128Kbps. This module you speak of (NM-4T) should support up to 8Mbps on a single interface or up to 2Mbps on all 4 interfaces at the same time. (just to be sure I checked Cisco's site on that module and here's what I found: "The 4-port synchronous (sync) serial network module (NM-4T) has four DB-60 ports and provides a data rate of 8 Mbps on port 0, 4 Mbps each on port 0 and port 2, or 2 Mbps on all four ports simultaneously. The NM-4T network module supports only sync mode. " http://www.cisco.com/warp/public/107/hw_4t.html So you clockrate shouldn't be a problem at 64Kbps. It seems that most of any suggestions I could make have been covered here (framing, frame-relay switching, etc). I guess I would just start at layer 1 and work up from there. i.e. make sure all cables, connectors and even serial interfaces on the routers are good, then proceed up to layer 2 with debugs, etc HTH, Mike W.

Frame-Relay problem - 3Com to Cisco (long) [7:32307]
We're switching our routers from 3Com to Cisco and we're having trouble at one of our sites. We've got a hub-and-spoke configuration from our central site to 4 other sites. 3 of the sites come up when we switch the hardware to Cisco (simply moving the CSU from the 3Com router to the Cisco router), the 4th does not. I'm including the Central Site config and 2 of the remotes (Site 1 comes up, Site 2 does not). We've changed out the router (including the serial ports), csu, serial cable, rj45's, everything. It's not a hardware problem. We changed the CSU on the central site, just to see if it would help. No go. Please let me know if you see something weird. I've replaced the DLCI #'s with letters, but they match up (i.e. if it's ABC in site 1, it matches to ABC in central site). I didn't include configs for sites 3 & 4, but they're identical with the exception of the DLCI's and IP's. (and they work as well). Something I had thought about... this site is in Canada and we're in the US as well as the other 3 sites. Would there be any caveats regarding international connections?

Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
Are you positive you have the DLCI assignments the same as in the 3COM router you replaced? What do 'show frame map' and 'show frame pvc' look like? Do you have any PVCs that are UNUSED/INACTIVE? On the remote side that is UP/DOWN, do you see any incoming packets at all or does it think the interface is up simply because DTR is high? What does show interface show on the remote side? Equal numbers of LMI enquiries sent compared to stats received? Thanks, John >>> "Bob Timmons" 1/17/02 10:35:42 AM >>> On S5/1 I get UP/UP.

Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
Bob,, You need to verify the LMI on the Canadian end...Cisco uses Strata (surprise) and Bell Canada uses Ansi or Annex A or Ddepends on where you are...I use to manage a network with several sites in the northland and we ran into this consistently. You can have different types of LMI in your network and it runs fine.

Thanks everyone for all the input... We're doing another test today at 4pm (EST) so I'll get more info and I'll try using different lmi-types. I seem to remember trying ansi, but I'll give it another go and I'll document all of the show frame map/pvc/etc in case it doesn't work again.

Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
Yes, the LMI is set at the interface level. However, since you're using 12.0 the router should auto-detect the LMI type.

Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
Well, the sub-interfaces do not need the LMI, it is only used to report the information about the dlci's to the interfaceactually I have turned off the keepalives in a lab environment and still pass traffic to a frame switch.keepalives =LMI for CiscoThe other thing is to be sure of the type of FrameRelay encapsulationCisco or RFC1490Cisco routers default to CiscoThis is set at the dlci level Terry Vore At 02:59 PM 1/17/2002 -0500, you wrote: >Thanks everyone for all the input...

Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
You are correct, the LMI is set at the interface level.
One command that I don't think has been mentioned is 'debug frame-relay
lmi'. It's pretty safe for a debug command - it shows you what is
happening between your router and the frame switch. You should see status
enquiries and status messages every 10 seconds, and every 60 seconds a
list of PVCs known by the switch, and their status. The 10 sec/60sec
might vary depending on switch type - I'm not sure.

Re: Frame-Relay problem - 3Com to Cisco (long) [7:32307]
Ok, success! Well, it turns out, we had a bad CSU. Strange thing, though. It worked ok on the 3Com equipment and last time we did testing, we put the CSU on the Cisco and it didn't work. We put it back on the 3Com and it worked fine. This time, we couldn't get it to work on the Cisco, tried putting it back and it died. We configured (yet) another CSU and up it came. I guess you can never try enough hardware sometimes. Thanks for all the input. It's much appreciated.
