frame relay stumper [7:60567]
How's this for nutty: We have a frame-relay point-to-point circuit going between our Cisco 7500 core router and a 2500 remote router, and the subinterfaces have IP addys of .1 and .2, respectively. Both sides' subinterfaces are "up/up", but I am not able to ping either IP address, even when I am on the host router for each address! Both sides have other working subinterfaces which I have tested similarly, and these use the same physical circuit, so I know the circuit is good. OH... and this connection WAS working at some point, but I can't tell when it stopped working, due to the fact that neither router recognizes that there is a problem. I tried bouncing both subinterfaces and reloading the 2500, but the problem remains. Any advice about what I may be overlooking would be a Godsend. Thanks!

RE: frame relay stumper [7:60567]
What about bouncing the 7500... if you did the 2500, and your problem wasn't resolved, it might just repair itself by doing the same to the 7500 (during a good maintenance window of course :) ) And, of course, everything that Chuck said too :) -Mark -Original Message- From: The Long and Winding Road [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 07, 2003 10:24 PM To: [EMAIL PROTECTED] Subject: Re: frame relay stumper [7:60567] sanitized configs would help immensely. including other subinterfaces that work as well as the ones that don't. from both sides. also, IOS versions, numbers of subinterfaces,etc. thanks -- TANSTAAFL "there ain't no such thing as a free lunch" ""Mossburg, Geoff (MAN-Corporate)"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > How's this for nutty: We have a frame-relay point-to-point circuit going > between our Cisco 7500 core router and a 2500 remote router, and the > subinterfaces have IP addys of .1 and .2, respectively.

RE: frame relay stumper [7:60567]
Have you checked the underlying PVC? show frame pvc, debug frame lmi, beat up carrier? I have seen PVCs misconfigured by the carrier so they connected to *somewhere*, so the sub-interface was up... but the PVC wasn't connected to the service it was supposed to be connected to, so not much was usefully happening across the link.

Re: frame relay stumper [7:60567]
Sounds like a possible carrier frame-relay switch mapping mishap. Maybe they added/changed some DLCIs to their switches and mucked up your PVC/DLCI mappings. Do you see CDP neighbor info over this DLCI (sub-interface) if CDP is enabled? That would indicate broadcast traffic is getting across the PVC end to end. Another idea would to clear the counters and do a ping test and see if other site PVC stats saw a increase in input packets relative to amount of ping traffic. Get on the horn with the carrier and have them verify the PVC mapping end to end, and verify the DLCI #s they have in their switches are the ones you are using still. Stay on the phone when they do this. Also, they may pass it off to some other intermediate carrier who has it messed up. The carrier can also monitor the PVC/DLCI traffic while you do some ping, data tests -- see if they see traffic being sent and received. Do a large 1500 byte ping for like a count of 200 just to get some data flowing while they look at it. If you have newer IOS, (12.03T and higher) you can try the Frame Relay End to End Keepalive (FREEK) feature too. This will force the DLCI/pvc down and sub-interface down if the keepalive packets aren't seen at other site. This probably isn't going to get you much but might show the smallish FREEK packet is getting across. Just another test similar to CDP packet test.

RE: frame relay stumper [7:60567]
Sorry for the lack of response until now; I'm on a mid-shift. I was able to get more info on this here (apparently it was a known issue, but not made known to me), and the problem is exactly as everyone has suggested: The circuit routes through TouchAmerica's network, and they have the PVC mapped wrong. Thanks for your responses!

Re: frame relay stumper [7:60567]
Hi Geoff, Just a small possibility Double check on what circuit is termining on the physical interfaces. What I mean to say is, if the two ends are not connected to the same circuit physically too, it might show you up/up (due to some other ends connectivity) but it won't be the result what you are looking for. Show cdp neighbor command can help you in this i.e. if some other Cisco router is getting connected ypu can see that in place of desired router. It had happened with me, so maybe it's the cause.

Re: frame relay stumper [7:60567]
I would do a SHOW FRAME RELAY PVC and see if the pvc is active. Also ensure that the IP's have the same subnet and configure the LMI type so that it matches on both ends. Possible even contact you Frame provider to see what type of LMI the switch supports.
