Hi
I have configured an network of 4 M10i routers for mpls using RSVP
for label distribution.
the topology is as follows:
R1----E3 line----R2----Ethernet----R3-----3xE1----R4
I have configured a test VRF on all 4 routers and associated a
loopback unit in each router to the test VRF.
I have ping between all loopbacks inside the VRF on R1,R2 and R3, but
not to R4.
My LSP seems to be working (show mpls lsp on R4 shows all LSP are up,
and I get successful MPLS ping using the ping mpls rsvp command).
However, when I use the show mpls lsp detail command I see the lsp as
up, but active routes is 0.
Also when I'm tracing to the remote PE I don't see any labels on the
trace. I believe that my BGP traffic does not use the LSP as the
egress point towards the remote PE, although the RSVP route is the
preferred route in inet.3
Below are some show commands from R4. any help would be appreciated.
Regards
Amos
