Line Protocol will not stay up on our 2811 Router

Hello all,

I am not a cisco guy, but I have to configure our 2811 router to accomdate these four T1 lines that we have bonded from our ISP (XO Communications).

I know the lines work because the default Nortel router they give us works fine.

I think I have the config done right, but for some reason the interface is up & the line protocol is down. Upon booting the router, the line protocols initally say up, but then go down.

Can some please look at my config (with IPs edited) to see if I'm loosing my mind? The ISP isn't lending a hand but they did say that the T1 lines are Frame-Relay and looking at the Nortel config, I noticed that they are using Multilink-PPP ... so that is what I configured (I think).

Many thanks in advance:

Post a sh frame-relay pvc, and see what the pvc status is. So you plug the Nortel in and it works, as a multi-link config? Also, post a sh frame-relay lmi.

I forgot to mention that the config I have posted above lists the dlci value as 23, when it is actually 16 (I pasted the wrong version) ... but everything else is correct.

Also, if I do a show int ser , the 'LMI enq sent' is always incrementing (every 10 sec) but the 'LMI stat recvd' is always zero.

I tried changing the LMI type from ansi to cisco or ccitt and neither work.
 
I would say that the pvc is not configured on the device acting as the frame-relay switch...I would contact the service provider and tell them that the status of dlci 16 is "deleted", indicating that the pvc is not configured on the frame switch...

Burt
 
More specifically...
This line...
"DLCI = 16, DLCI USAGE = LOCAL, PVC STATUS = DELETED, INTERFACE = Serial0/0/0:1.16"
shows that dlci 16 usage=local, meaning it is indeed configured on your router, and pvc status=deleted means it is not configured on the frame switch. If the dlci usage = unused, that would mean that a dlci that is configured on the switch is not configured on the router. In other words, it is not a matter of the telco and you configuring different dlci's, but it is a matter of only you configuring a dlci, and the frame switch does NOT have it configured.

Burt
 
burt has it.. when a pvc shows deleted it means that the frame switch doesn't know about that dlci. either you have the wrong dlci or the telco has a misconfiguration..

in your old config were all 4 t1s bonded or were they running seperate.. ie each having their own dlci?
 
Burt - I'm about to pull all my hair out.

So, the telco finally came back to me with a "sample" cisco config ... the serial lines are setup with encapsulation as ppp rather than frame-relay which explains why my lines wouldn't come up.

Even though they explicity told me that I was running a FR circuit.

What a headache ...

Thanks for the help & suggestions anyway!
