I set up a simple LAB for MPLS VRF
the diagram is CE-PE1-P-PE2-CE .
The configurations of all 3 routers are in the attached , I also did some show cmd output . I tried to ping test each pair of vrf ip , from 1 site to other but got time out. Could you pls verify my config and figure out what I missed ?
Thanks

Hi,
have a look at this:
sh tag-switching tdp discovery
Local TDP Identifier:
2.2.2.2:0
Discovery Sources:
Interfaces:
FastEthernet0/0 (tdp): xmit/recv
TDP Id: 10.10.10.1:0; no route
The info "no route" tells that TDP/LDP is not operational. Thus VPN connectivity can not exist.
Make sure the proper IP address is used as TDP/LDP ID and is present in the routing table.
Example on every PE/P:
mpls ldp router-id Loopback0 force
if Loopback0 can be reached through IP routing (test with extended ping Loop to Loop).
Check label switching in your MPLS core with traceroute to your BGP next-hop addresses.
Check the existance of a TDP/LDP session with "show mpls ldp neighbor".
Hope this helps! Please rate all posts.
