Oopss Sorry guys...I donto know where it lost in b/w..Any way..I have write it here again. Thanks for the kind replies.. For eg, our FR switch is setup for Full mesh,But out network is setup as Hub & Spoke environment.In that case there must be some unused DLCI's on spoke routers which we would still be seeing as active on these routers although they would be of no use offcourse for this envioronmetnt. Is there any way If we can get rid of these DLCIS on the spokes.i.e to disable them or USE any method which block them to be appearing on spoek routers.(without touching FR switch) I know Must be confusing for majority here ..But ..

RE: For FR Grus.... [7:16635]
get rid of them? why? why not use them? after all, you are paying for them! or you can call the telco and have them delete the dlci's you aren't using. but as long as the dlci's are configured on the frame switch, LMI will report their existence to you. this is a Good Thing, by the way.

Re: For FR Grus.... [7:16635]
You can disable inverse arp on each interface on the spokes and then clear the cache. That should prevent the spokes from seeing the unused dlci's, but will require a static map of dlci to ip for each dlci you want to use.

it used to be that you could do a clear frame-relay-inarp to accomplish this. however, since the advent of 12.x, I believe the only sure way is to reload.

If dont want to use the DLCs and you are using a physical interface for frame-relay just disable frame-relay inverse arp. If you dont want to do that use point - to - point subinterfaces and define the DLCI you want to use on the subinterface.

I don't believe so, at least on the newer 12.0 stuff, you can disable frame-relay inverse-arp and then clear frame and your ok. I think it may have behaved differently in the past though.

Hi Cisco Lover, Looks like the DLCIs advertised by the FR-Switch, try use "no frame-relay inversearp" to disable the spokes router keeps hearing the DLCIs from FR-Switch.

You don't have unused dlci's because you are in a hub and spoke...

RE: Fwd: For FR Grus.... [7:16635]
Hmm, how interesting. Is that something you see often, or only in few cases? Will it have ANY effect on the router at all, or will it just be "empty"/unused information? I would think that if they map a DLCI to your router that is live with someone elses router, you could end up receiving unnecessary/unwanted traffic if a pvc should be established by accident? If you can come up with a real life horror story about this problem, please do so. Thanks, Ole ~~~ Ole Drews Jensen Systems Network Manager CCNA, MCSE, MCP+I RWR Enterprises, Inc.

Well, you can't remove yourself from seeing the DLCI's but defintly disable inverse-arp on any physical or multipoint interfaces, and use static frame maps, unless you want to be subject to the consequences.

RE: Fwd: For FR Grus.... [7:16635]
I think that at this point, it would help if you could tell us little bit about your setup. 1) How many routers do you have, and how are they connected to each other? 2) Include the "show conf" of the router acting like a Frame Relay Switch. 3) Include the "show conf" of the hub router. 4) Include the "show conf" of one of the spoke routers.

No one has gotten this problem yet. Remeber, making it so the clients are on differnt layer 3 networks works, but when they are on the same it doesn't. What mechanics are involved in how the packet will be treated different if on the same network vs. different networks. I'll still leave the answer open, someone will get this.

RE: CHALLENGE PROBLEM (was Re: For FR Grus.... [7:16635]) [7:16714]
I can think of two reason why it wouldn't work. 1. Because you're using bridging on the frame relay links, it must adhere to the spanning tree rules. This means that you cannot send traffic out the same interface you receive it on. In this configuration it would mean that information received on a DLCI it would not be able to be forwarded out any of the other DLCIs because they are on the same physical interface 2. You're using "frame map bridge" statements which disables inverse arp. You have to add static "frame map ip" statements for all the layer 3 addresses. This wouldn't explain why it works when the DLCIs are on different layer 3 networks though.

YES! You got it correct! One must remember that when bridging on a router, its just like a real bridge/switch. Interfaces are like ports on a bridge, and a packet entering a port will never go back out that same port. Using sub interfaces fixes it. Now why does it work when you put them on 2 different layer3 networks? Because this forces packets to tag the BVI, and thus get routed (BVI must be setup with secondary addressing). And routing can go out the port, tag the BVI, and go back down the port, but bridging will not work! > (This limitation is intended to avoid bridging loops, I think, because > STP will treat physical interface as a single bridge port.) > > The common solution is the use of p2p subinterfaces.

If the clients are on different layer 3 network, then that should be configured as point to point network. If they are on same network then they can use point to multipoint. I think in the given senerio, it should be configured as point to point network. Arun --- Brian wrote: > No one has gotten this problem yet.

If they are on same network then they can use > point to multipoint. Well, not really. In practice its fine to put bridged customers on a single multipoint and use different layer3 networks. Why would you do this? Well, in early DSL rollouts, things on Cisco routers like IDB's, BVI's, etc were limited resources..some routers could only do 300 even. So you would lump many DSL customers in on one multipoint interface. > I think in the given senerio, it should be configured > as point to point network. Yes, ideally, but its sort of like a typical Cisco or CCIE type problem, where the configuration is valid, but doesn't necessarly make sense or would be the best way to do it. Its just to demonstrate the issue or port blocking on a bridge. > > Arun > > --- Brian wrote: > > No one has gotten this problem yet.

Sounds like Spanning tree is screwing it up. Since this is a multipoint interface. It think spanning tree will consider it as one port. Any packet that comes in the router and is destined for the same subnet doesn't hit the BVI and is bridged. 1st rule of bridge forwarding : If the destination MAC address is unknown, forward out all ports except the ingress port. Since all the packets come in the same port as far a spanning tree is concerned, unknown or ANY packets for that matter, will not be set out the same port. Packets on different subnets hit the BVI and are routed and so will bypass the bridging rule. A bridge will NEVER forward a frame out the same port in came it. Solution: Set up P to P subinterfaces. These should be treated by bridge as different ports and frames will get forwarded. IGRP and split horizon have nothing to do with it. At least I think this is the problem :) Tony M #6172 - Original Message - From: "suaveguru" To: Sent: Tuesday, August 21, 2001 7:55 PM Subject: RE: CHALLENGE PROBLEM (was Re: For FR Grus [7:16635]) [7:16755] > is it something to do with using classless rather than > classful routing protocols? > > > regards, > suaveguru > --- Patrick Ramsey > wrote: > > How about get rid of igrp and configure ospf in nbma > > mode? :) > > > > -Patrick > > > > >>> "Brian" 08/21/01 02:10PM >>> > > No one has gotten this problem yet.

Brian, I just wanted to say publicly that this was an outstanding test question. outstanding because of all the red herrings it contained, as we saw from the wild guess responses. so everyone knows, my own private reply was incorrect as well. doh! thanks for this - these kinds of challenges are what make groupstudy worthwhile to me at least.

Ok, I will post one, its got FR in it. First I'll post the problem, followed by the config: THE PROBLEM === Users on DLCI's 200, 224, 201, 225 cannot communicate to eachother. They can talk just fine to the rest of the network, but no packets can pass between them. Later discovery reveals that so long as they are on different layer 3 network addressing, communcation can occur, but if they are on the same network, such as 192.168.3.0, then they cannot communicate What is the problem? I will reply to let everyone know who got the correct answer.
