RE: Broadcast keyword in subinterface [7:61829]
I checked on my routers. They let me enter the broadcast keyword on a subinterface using the "frame-relay interface-dlci dlci" command. But they are running 11.0. So maybe it was supported at one time, but then Cisco realized it wasn't necessary and removed it. Historical IOS research isn't fun, so I won't bother to do more. :-) Priscilla Simmi Singla wrote: > > Hi Priscilla, > I myself also didnot check on the router just saw that in > documentation .yeah true there is no keyword broadcast on the > subinterface as per now i checked on my router . > http://www.cisco.com/en/US/products/sw/iosswrel/ps1824/products_command_summary_chapter09186a0080081010.html#xtocid1342715. > > > see this link above here its mentioned broadcast keyword ,i > think U are correct it might be for main interface or what > ,either the documentation is wrong. > In the link u specified it was not. > > Priscilla Oppenheimer wrote: > > > > You better show us actual router output and tell us your IOS > > version.

RE: Broadcast keyword in subinterface [7:61829]
Hi Priscilla, I myself also didnot check on the router just saw that in documentation .yeah true there is no keyword broadcast on the subinterface as per now i checked on my router . http://www.cisco.com/en/US/products/sw/iosswrel/ps1824/products_command_summary_chapter09186a0080081010.html#xtocid1342715. see this link above here its mentioned broadcast keyword ,i think U are correct it might be for main interface or what ,either the documentation is wrong. In the link u specified it was not. Priscilla Oppenheimer wrote: > > You better show us actual router output and tell us your IOS > version.

RE: Broadcast keyword in subinterface [7:61829]
You better show us actual router output and tell us your IOS version. Per Chuck and Cisco's latest WAN Command Reference, there isn't a "broadcast" argument to the "frame-relay interface-dlci" command. Here's the syntax per Cisco: frame-relay interface-dlci dlci [ietf | cisco] [voice-cir cir] [ppp virtual-template-name] See the Command Reference here: http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fwan_r/frcmds/wrffr2.htm So, something is definitely squirelly if you are able to type in the broadcast keyword. I'll try on my routers too if I get a chance.

RE: Broadcast keyword in subinterface [7:61829]
Hi , Thanx both of u for answering But my design is like that I am using point to point subinterfaces for connecting to remote sites.right now only static routing we have but it might be tommorow we may switch for dynamic routing protocols so in that case as both of us sain no need of broadcast keyword on point to point subinterfaces. if its not needed then why in the command there is option for broadcast keyword. Example: Int serial 0/0 no ip address int serial 0/0.1 ip address 1.1.1.1 ?255.255.255.0 frame-relay interface-dlci 16 broadcast should i give broadcast or not ,Correct this is point to point link and adjancies will be established automatically. why this broadcast option is there ,still a confusion although this keyword is optional.This maeans this keyword will never be used on point to point interfaces. am i right if not please correct me Priscilla Oppenheimer wrote: > > Priscilla Oppenheimer wrote: > > > > Simmi Singla wrote: > > > > > > Hi all, > > > Can anybody explain me when i use the broadcast keyword in > sub > > > interface(fram-relay interface-dlci 16 broadcast) then if i > > > have only static routing will it affect that.I read that it > is > > > used only for OSPF to pass broadcasts , if multicasting > > > disabled.But In a scenario if I have no dynamic routing and > > > give this command what will happen. > > > will it pass unknown broadcasts on frame-relay. > > > > Remember a router doesn't pass broadcasts, i.e. forward > > broadcasts.

I meant to say "dynamic routing" there. That is, use the broadcast keyword if you need the router to send routing protocol route updates or hellos as broadcasts (or multicasts). He had asked about static routing, so I wanted to add that thought but then the darn phone rang while I was typing and I wrote dynamic addressing instead of dynamic routing. :-) Priscilla > For example, use seomthing like "frame-relay map protocol > address broadcast." > > The other solution, however, is to use subinterfaces.

Remember a router doesn't pass broadcasts, i.e. forward broadcasts. So think about when you would need to let a router send broadcasts on its own, from its own interface. The usual case is to support dynamic routing. If you are using static routing, then you don't have to worry about it. Frame Relay is used on routers to create virtual circuits to remote sites. A point-to-point virtual circuit can send broadcasts without any problem. Frame Relay is often designed in a hub-and-spoke topology, however, with the hub router connecting many remote sites. A typical design is to place all the WAN serial interfaces in this design in the same subnet, thus creating a multiaccess WAN "cloud." The cloud resembles a LAN subnet, but does not support broadcasting like a LAN would. The cloud is a nonbroadcast multiaccess (NBMA) network. When a router sends a broadcast into the cloud, only a directly connected router on the same virtual circuit hears it. Many protocols were designed with the assumption that two hosts on the same subnet have Layer 2 connectivity and can easily hear each other's broadcasts. This isn't the case in a Frame Relay hub-and-spoke topology. So to fix the problem, if this is your design, you better add the "broadcast" keyword if you are using dynamic addressing. For example, use seomthing like "frame-relay map protocol address broadcast." The other solution, however, is to use subinterfaces. This turns the links back into normal point-to-point links. Then they support broadcast no problem. Chuck can correct me if I got this wrong! :-) Priscilla > moreover exactly how it is used in point-to-point sub > interfaces. > Thanx a lot in advance--:) Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=61865&t=61829 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Therefore the switch does not exist.

Broadcast keyword in subinterface [7:61829]
Hi all, Can anybody explain me when i use the broadcast keyword in sub interface(fram-relay interface-dlci 16 broadcast) then if i have only static routing will it affect that.I read that it is used only for OSPF to pass broadcasts , if multicasting disabled.But In a scenario if I have no dynamic routing and give this command what will happen. will it pass unknown broadcasts on frame-relay. moreover exactly how it is used in point-to-point sub interfaces.

Try this: interface FastEthernet0/1 description Router on stick (2600) switchport mode trunk switchport trunk encapsulation isl Off the top of my head, I can't remember if the 3550 only supports dot1q, or ISL, or both. So if the above doesn't work, use dot1q rather than isl on the router, and forget the encapsulation command on the switch.

What model 2600 exactly are you using? If this is not a 2620 or better with a fast ethernet interface it won't work.

It does not show up in the show run but when I do a sh ip int brief it shows up but as deleted. Even though it is not in use or affecting anything, will it still always show up in sh ip int brief? Is there a way to get it out of the sh ip int brief?

subinterface in ospf [7:39029]
when using the command frame-relay interface-dlci XXX in point-to-point subinterface, does it mean the inverse-arp to map the remote ip to the local dlci dynamicly?

Re: subinterface in ospf [7:39029]
inverse arp does not apply. that is, when you invoke the frame-relay interface-dlci command, this overrides inverse arp for that particular dlci. other dlci's might still be mapped via inverse arp ( to the physical interface ) this command is REQUIRED on point to point subinterfaces.

Yes, you can do this on a subinterface. I was doing it just yesterday in conjunction with an IPsec, GRE, NAT, and policy routing scenario. And -- surprisingly -- it worked!

Policy routing - interface or subinterface? [7:38528]
Just verifying something I am seeing in my lab. All examples of policy routing that I can find, both in Doyle and on CCO, show policy routing as taking place on the physical interface. I can find no examples indicating that policies can be set on a subinterface. However, I am finding in my lab that separate policies can indeed be set up on different subinterfaces.

Re: point-to-point subinterface [7:37831]
Hi, Is there already a s0.1 interface defined? Try creating a s0.2 or something that doesn't exist. Once you create a sub-interface you can't change it from multipoint to point-to-point and vice versa. Also, if you remove sub interfaces they aren't completely removed from memory until the router is reloaded/reset. Perhaps, you deleted the s0.1 interface and are running into this.

Re: point-to-point subinterface [7:37831]
At some point since the last time you rebooted this router, you must have configured the same subinterface as multipoint. Either choose a different subinterface number or remove the subinterface and reboot the router. That will allow you to use the same number with a different link type.

Have you define the "encapsulation frame-relay" command first? If that doesn`t help, then your IOS doesn`t support for "Frame Relay SVC Support (DTE)". Try upgrading the IOS, you can lookup which IOS that supports subinterfaces from Cisco IOS Feature Navigator link.

Re: [F.R.] What's the difference of multipoint subinterface to [7:7927]
If I understand your question right, one of the reasons is for split horizon. I you have a hub and spoke frame relay network and lets say your hq router has a pvc to dallas and a pvc to boston both comming in to your s0 interface. well split horizon says that you will not send out a routing update out of the same interface that it came in from. So if you receive a routing update from boston into your s0 interface it will not forward the update to dallas because split horizon will not let it go out the same interface that it came from even though it is going to dallas not boston. It is to prevent routing loops. do a search on split horizon and routing loops for a more detailed explaination. Hope this helps.

Re: HSRP running on subinterface of 2651 [7:3800]
Folks, Sorry I think I mistype something below. Let me rewrite it here again. I have 2 2651, say A and B, connecting to a group of switches. Trunking and VTP are running on the switch group. Each 2651 is connecting to the switches on same VLANs. Say there is VLAN 1 and VLAN 2. Both 2651 are running trunking and dot1q encapsulation. Ok, FE0/0.1 of A and FE0/0.1 of B are on VLAN 1 FE0/0.2 of A and FE0/0.2 of B are on VLAN 2 I setup HSRP on both subinterface and router A is always the highest HSRP priority. I have a PC connecting or with IP address of VLAN 2 segment. I try to ping from the PC to an interface of B say FE0/0.1 but no response. But I can ping the subinterface of B FE0/0.2. I can also ping from A to B FE0/0.1. Is there any issue running HSRP on vLAN subinterface or do I miss any configuration??

HSRP running on subinterface of 2651 [7:3800]
Hi folks, I encounter some problem and hope that you folks can give me some idea. I have 2 2651, say A and B, connecting to a group of switches. Trunking and VTP are running on the switch group. Each 2651 is connecting to the switches on same VLANs. Say there is VLAN 1 and VLAN 2. Both 2651 are running trunking and dot1q encapsulation. Ok, FE0/0.1 of A and FE0/0.2 of B are on VLAN 1 FE0/0.2 of A and FE0/0.2 of B are on VLAN 2 I setup HSRP on both subinterface and router A is always the highest HSRP priority. I have a PC connecting or with IP address of VLAN 2 segment. I try to ping from the PC to an interface of B but no response. But I can ping the subinterface of B FE0/0.2. Is there any issue running HSRP on vLAN subinterface or do I miss any configuration?? Thanks bros.

Re: backup subinterface on another subinterface
It will if they both have different IP subnets, thus the floating route has it's own next hop. If you want to go further you can use route-maps and do policy routing. If PVC1 was down you could match on the sub interface that was up and change the next hop. Same for other PVC... Why are you backing up one PVC with another PVC on the same physical circuit? I work with Frame regularly and a majority of the time frame outages involve the entire circuit (loss of signalling / LMI, circuit down, line problems, etc) and not just one PVC, unless each PVC is going to a different site/spoke and the spoke was having line/LMI issues. If this were the case then routing traffic for this site over the other PVC might make sense if that spoke/site had a link to the original destination or served as a backup for that location being down. --- Adam Wang <[EMAIL PROTECTED]> wrote: > Thanks for all your input on setting up a floating > static suggestion, but the 2 PVCs that I have are > both active and in production, and each is carrying > different type of traffic. > > They are both acting as primary links.

Re: backup subinterface on another subinterface
could be way off, but what if you look @ this on the domain side (if possible) & setup HSRP. Assuming you are able to run ILMI & the interface will indeed go down when it needs to, I'd let the load balance take place before hitting the ATM network. .02 Phil - Original Message - From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, February 15, 2001 12:41 AM Subject: Re: backup subinterface on another subinterface > What differentiates the traffic? > Different destination IP networks?

Re: backup subinterface on another subinterface
What differentiates the traffic? Different destination IP networks? Then floating statics should be OK. Different protocols? Then you need to look at each type of traffic independantly - you can set up floating statics for IPX, and maybe other protocols. What are your different types of traffic?

Re: backup subinterface on another subinterface
Thanks for all your input on setting up a floating static suggestion, but the 2 PVCs that I have are both active and in production, and each is carrying different type of traffic. They are both acting as primary links. I want to set up something that if one fail, it will jump to the other one. I don't think floating static will work in this case.

Re: backup subinterface on another subinterface
The way my company does it is to weight routes for the two PVC's. Serial0/0.1 point-to-point ip address 192.168.255.1 255.255.255.252 no ip route-cache no cdp enable frame-relay interface-dlci 20 ! Serial0/0.2 point-to-point ip address 192.168.255.5 255.255.255.252 no ip route-cache no cdp enable frame-relay interface-dlci 21 ! ip route 10.0.0.0 255.0.0.0 192.168.255.2 ip route 10.0.0.0 255.0.0.0 192.168.255.6 200 ! end wr This says to route the traffic over S0/0.1 as it is directly connected. Route the traffic over S0/0.2 if the primary link should become unreachable. You have to be careful with the administrative distance on the backup route. If you are running a routing protocol (OSPF, RIP, etc.) you will have to take into account what the default distances are for these protocols. Keep in mind that a route that points to an interface is distance 0 and a route to an IP address is distance 1.

backup subinterface on another subinterface
Hi group, I have 2 PVCs setup using Frame Relay on a serial interface with 2 subinterafces, and I want these 2 subinterfaces to backup each other when 1 fails. I did backup interface s0.2, but it won't allow a subinterface on the backup command, only the physical interface. So backup interface s0 is possible. Why is that and how can I do this Thanks in advance Adam __ Do You Yahoo!? Get personalized email addresses from Yahoo!

Re: When do we have to use subinterface on FR config?
Hi, How about when setting up traffic shaping and or differing rules for differnt people on different PVC's on the same interface. To my way of thinking the extra functionality for the little extra configuration it is usually well worth it. But then again it's horses for courses. It is however a lot more work if you don't have sub interfaces configured then find out you need to do something to a PVC that lives with all the others. The good thing about subinterfaces is they are not physical you can therefore do stuff to one user ie shut, no shut change and configs without affecting all on the physical interface.

Re: When do we have to use subinterface on FR config?
Not always. You should only have to use subinterfaces for point-to-point FR connections. Otherwise you can use on interface for many connections... point-to-multipoint.

Re: Subinterface question
Jeff McCoy, I agree the administrative distance is 0 for all directly connected interfaces when using any routing protocol, but as the first entry says from I think Jeff Walzer routing will first look for the most specific entry- most contiguous bits specified left to right. So the entry that only specifies /24 bits will be superceeded by the entry specifying /28 bits regardless of the administrative distance. - I just got a refresher on this fact a few minutes ago. >>>Brian >From: "Jeff McCoy" <[EMAIL PROTECTED]> >Reply-To: "Jeff McCoy" <[EMAIL PROTECTED]> >To: [EMAIL PROTECTED] >Subject: Re: Subinterface question >Date: Tue, 7 Nov 2000 09:02:39 -0500 > >yea..its the routing mechanism that determines the metric...but (correct me >please) dont all routing protocols give a metric of 0 to directly >connected >networksand therefore, the metric would be 0 in this situation >regardless of the routing method selected? > >""Howard C.

No type of interface or subinterface inherently has a metric until you define a routing mechanism with respect to that interface -- and that mechanism defines the metric. So OSPF and EIGRP, in practice, use bandwidth as a metric. RIP uses hop count, which may be what you are thinking of. The zero value for a directly connected network is the administrative distance, which is different from a metric. Administrative distances rank preferences among sources of routing information, lower values being more preferable. For example, an OSPF route with an administrative distance of 110 will never be preferred to a directly connected route. A RIP route (to the same destination) will never be preferred to an OSPF route. (note...I'm assuming here that you use the standard route selection algorithms without overriding anything) Metric is used as a tie-breaker between routes of the same administrative difference. Prefix length is considered before administrative distance. A route of 192.168.0.0/28 from RIP is preferable to any OSPF route to 192.168.0.0/24. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Subinterface question
Our internal network has 10 subnets that can be utilitized (10.10.1.x - 10.10.10.x). The router IP address is 10.10.1.1. When I create a subinterface for 10.10.2.1 what is the metric for the 10.10.2.x subnet to get to the 10.10.1.x subnet? Being that it is the same router will it be 1 or does each subinterface increment the metric by 1 thereby making the metric 2 for each subinterface?

hi Brian. I have a quick question from what you mentioned regarding multipoint subinterface that I have always been wondering about. You mentioned, "Point to multipoint" and it can communicate with many routers within that same subnet." Let's say there is a router in a headquarter, and 2 routers in a branch office, so let's say there are three interfaces are participating in Frame-Relay.

Subinterface config
I know that the subinterface inherit the configuration from the main interface. But what appends when subinterface is configured and the interface is not? I'm asking this because i had one problem with one router and after many changes to the configuration it started working. I've compared the first configuration and the one running now and the only difference is: frame-relay lmi-type cisco frame-relay ip rtp header-compression in the serial interface (but these commands were always in the subinterfaces). By the way, the problem was with low bandwidth in one serial. ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Any difference between secondary address and subinterface for a port?
Secondary addressing and subinterfacing serve different purposes. In my less than humble opinion, the major applications for secondary addresses are workarounds for problems caused by the dinosaur of classful addressing. These are discussed in detail in Chapter 5 of my _Designing Addressing Architectures for Routing and Switching_, but some applications include: -- making more hosts available than are available with a fixed subnet mask -- fixing discontiguous networks -- dealing with especially stupid host stacks that assume default masks The underlying concepts of secondaries and subinterfaces are different. Secondaries (called multinets in Bay-speak) map multiple subnets/networks to a single broadcast domain, NBMA medium, or point-to-point link. Subinterfaces separate the broadcast domains on a medium with layer 2 multiplexing (e.g., DLCI, VLAN ID, ATM VC, etc.). There are some complex VLAN configurations where it can even be useful to have secondaries on subinterfaces. Personally, I shudder at the thought.

Re: Any difference between secondary address and subinterface fora port?
Well from my understanding a subinterface would be better from an administrative point of view. I.E. Say you want to run two IPX networks on the same physical interface using the secondary command. If you where to change the encapulation on the phsyical interface you would affect all IPX networks. Now if you where to have a subinterface this can be avoided. The IOS sees these subinterfaces and different logical interfces on the same physical interface. To round it up, you can perform differnt functions on a subinterface. IF you where to use the secondary, anything you change to affect the interface would affect that secondary addres bound to it. Group correct me if i'm wrong, or sorta right.

Re: CDP not working on subinterface
I've checked the CIR and we're doing fine there, especially since this is a 256k fractional t-1 running at about 1% utilization. Our circuits are not policed, so even if we were above CIR, nothing gets dropped unless the frame relay network became obscenely congested. As I mentioned before, all other PVCs on this major interface work just fine except one other that has the same symptoms. When I first brought up this circuit, I was at the remote site with a laptop in the console port. Where I first did "show cdp n", both neighbors were in the list, but after a minute or two, one of them disappeared and has yet to return. The line itself is functioning correctly, as far as I can tell. We're not seeing any interface errors whatsoever and it's been up for a couple of weeks, now. Perhaps I've found an IOS "feature." We're using 11.2(18). I think I'll check CCO and see if they've noticed this in the past.

RE: CDP not working on subinterface
The PVC is working perfectly, except for CDP. It's configured exactly like the 89 other subinterfaces on that major interface, so I doubt it's a configuration issue, but it still may be. The remote side has two PVCs on one major interface and CDP is working on one subinterface only and they, too, are configured exactly the same except for DLCI and IP address.

RE: CDP not working on subinterface
John, Is it just CDP not working or is the whole PVC showing as inactive? I've seen where if LMI was configured incorrectly at the remote end when the router was first brought up it would come up but after a minute or so go down because it wasn't receiving lmi keepalives from the switch. In this case it was a telco switch problem and I do know that LMI is supposed to be autosensing with the newer software. If it is just CDP down I would have suggested something to do with the timers but you said the remote end isn't receiving any packets at all? Hmmm. Stumper. Just throwing out some ideas for ya.

RE: CDP not working on subinterface
We use entirely point-to-point subinterfaces, and we have no special configuration on them regarding broadcasts. On this particular major interface, there are 90 subinterfaces and CDP is working just fine on all but two of them. They all have identical configs except for the DLCIs and IP addresses. "show cdp int" shows that CDP packets are being sent, but they aren't being received at the opposite end, according to "debug cdp packets". Another oddity about this is that it worked correctly when I first brought the circuit up for about a minute or so, and then it stopped.

RE: CDP not working on subinterface
This is purely a guess... Are you allowing broadcasts across the PVC by using the broadcast keyword on the frame-relay map command? CDP sends to a multicast address.

RE: CDP not working on subinterface
No, I haven't done that, but I did "show cdp int" and the router said that it was sending cdp packets out that interface. Both routers on each end of the link reported this. I'll try debugging tomorrow. Thanks for the tip!

RE: CDP not working on subinterface
Did you run "debug cdp" to verify that it is being sent? -Mag Magnus Thorne eVoice, Inc. 1394 Williow Road Menlo Park, CA 94025 Direct: 650.330.3974 Main: 650.330.3700 Fax: 650.330.3901 eVoice.

I brought up a new PVC today and at the remote side I could see both PVCs to that router. After a few seconds, though, one of them disappeared from the "show cdp neighbors" output. No changes were made to configs at either side, it just did this on it's own. This particular PVC is terminating at a subinterface on both routers, and other subinterfaces on the major interfaces at each end still report their cdp neighbors correctly; the problem is only on this particular subinterface. I have noticed this in the past with a different PVC, so it's happened at least twice in our network. any ideas why it works temporarily and then quits?
