My MPLS Issue

[chris.lau]

I have 4 7206vxr npe-400 routers in my network lab.

PE1<>P1<>P2<>PE2

PE1 and PE2 are running MBGP

I am running OSPF as the IGP protocol

If I connected all the routers using a serial back-to-back connection, the ip routing was working, but mpls was not! when I issue "show mpls ldp nei"...it failed!!

But, if I connect the routers using frame relay switch, everything work fine!!!

Can I know why?

hi!

When you are connecting back-to-back, using a serial, can you paste the interface config and the output of the command "sh mpls ldp discovery" ?

Also make sure that all the loopbacks are reachable through ospf?
