hi Doug

looks like you are getting the VPN label but not the next hop label

on PE1, try doing
sh mpls forwarding-table | include 192.168.254.254

on PE2, try
sh mpls forwarding-table | include (loopback address PE1)

under the 2nd column, you should see outgoing label(s)
Local  Outgoing    Prefix            Bytes tag  Outgoing   Next Hop
tag    tag or VC   or Tunnel Id      switched   interface

if either or both loopbacks have no label value, there is an outer label
problem,
- ensure you are running MPLS on the interfaces, LDP adjacencies are up
(show mpls ldp neighbor) and that loopbacks and interfaces connecting PE1, P
and PE2 are in the routing process.

regards
Phil

Betreff: [MPLS-OPS]: Ping vrf <vrfname>


I have an issue with our IP VPN test lab.

CE1 running rip v2 (eth0/0 - 10.223.0.1) in vrf berkeleyHomes, which can see
all connected serials and it's neighbour within the vrf 10.212.0.1. It can
ping PE1 its connected neighbour but not CE3 (10.212.0.1).

PE I can ping vrf berkeleyHomes 10.223.0.1 but not 10.212.0.1 yet it appears
to see all routes - sh ip route vrf berkeleyHomes and learns about
10.212.0.1 via BGP on PE2 (loop0 192.168.254.254)

>From PE1 you can telnet across the two P nodes to PE2 (192.168.254.254).
Once on PE2 you find the opposite, all routes are visible but whereas PE2
can ping 10.212.0.1 it can't ping 10.223.0.1

I had this up and running last week and then the next morning came in to
find that I had this problem. I've run all the sh tag commands I can think
of and everything seems to be in order. This is actually starting to hurt
now, so any help greatly appreciated from anyone who may have experienced
this before.

Thanks


Doug
