MLPPP over Frame Relay issue
I have PPPoFR running on a cisco 1700 (pretty old series), virtual template is configured properly, I have 2 T1’s bonded in a PPP multilink.I do not own the frame relay switch (ISP does). On the physical interfaces serial 1 (access-member 1 is up/up) serial 0 (access member 2 is up/down) if I do a shut no shut on this interface it becomes up/up and after 10 seconds goes back to up/down. The output of the show frame-relay pvc command shows pvc=active for serial 1 and deleted for serial 0, if I use the no keepalive command under the up/down interface (serial 0) and shut no shut it stays up/up but no traffic goes through, the show FR lmi command displays that this IF has not received a reply in 5 weeks, but the last request was 2 seconds ago. Is there any other explanation for this than ISP deleted their end of the PVC for the T1 that is connected to serial 0?
Also I was working with the ISP on this, because they state that their end of the PVC has not been deleted (which I don’t think so) and they shutdown and turned back on the T1 (the one that goes to serial 0) from their end while I had term monitor on my router. I saw the interface go down/down and then back up/up and after 10 seconds go back to up/down, that proves that the WIC is fine and there is physical connectivity to the ISP. Thanks!

I would double check your config including your local dlci's, lmi type etc. Have you tried removing that circuit from the bundle and see if it goes active? Posting a config might help. Also check to make sure your linecode and framing is correcto on that serial 0 interface. That second pvc isnt getting lmi from the FR switch.
Yeah. LMI type on both sides was ANSI and all configs were fine, it is fixed now ISP had their end of the PVC deleted.
