Yeah, I knew that would be confusing. The reason it is set up this way
is because I'm mimicking the real world environment at work. On it, the
provider has given each remote router the dlci 16, because it goes
through many service area's. The DLCI's shouldn't be a problem to my
knowledge just a bit confusing, but here is the show frame-relay map the
2 routers:
R1:
sh frame-relay map
Serial0.18 (up): point-to-point dlci, dlci 18(0x12,0x420), broadcast
status defined, active
Serial0.17 (up): point-to-point dlci, dlci 17(0x11,0x410), broadcast
status defined, active
Serial0.16 (up): point-to-point dlci, dlci 16(0x10,0x400), broadcast
status defined, active
R2:
Serial0.17 (up): point-to-point dlci, dlci 16(0x10,0x400), broadcast
status defined, active
When debugging ip packets, it show's encapsulation failed, but from what
I see there is no encapsulation mismatch in my configs.

Subject: Re: Frame-relay / IP assistance
your frame switching is kind of confusing..your using the same dlci
number for
two routers...I suppose it may work, but I used
different dlci's for my routers in the frame switch...
do a 'sh frame-relay map' and see what is mapped to the dlci's..

Subject: Frame-relay / IP assistance
I am having a problem with my Frame-relay set up and I think Ibm just
missing some little thing that I continually overlook, hope you guys
can
help me. I have a lab set up with a frame-relay switch going to 4
routers, I will only deal with 2 to keep this as short as possible. I
can not ping any interfaces in this lab, but I can show cdp neighbors
and see all the neighbors, show cdp neighbors detail and see their IP
addresses and my show frame-relay pvc looks good toob&here is the
output
of R1bs show frame-relay PVC:
