Hello all,
I have the following setup in terms of LSP's:
London - Paris
Paris - London
Very basic so that I can pass traffic across my 2547 network. There are
other LSP's that are setup in the same way ingress/egress of Paris and
London which work fine.
The problem is that I can ping from Paris to London whereby London to Paris
does not want to know (see pings below):
[local]#ping mpls rsvp PARIS-LONDON
Sending 5 100-byte MPLS echos to PARIS-LONDON, source x.x.x.3,
timeout is 1 second, send interval is 0 msec:
!!!!!
[local]#ping mpls rsvp LONDON-PARIS
Sending 5 100-byte MPLS echos to LONDON-PARIS, source x.x.x.2,
timeout is 1 second, send interval is 0 msec:
.....
I have triple checked the config which is in line with other LSP's that
work, however this is stumping me.
The IGP is fine - OSPF can see the loopbacks, and MBGP is looking good. The
VPN config is fine with the RT and RD looking good.
This is the viewpoint from London for the LSP's ingress and egress

There seems to be limited commands for troubleshooting the LSP so if anyone
knows what else to try - please let me know. I see some path error messages
but dont know how to decipher them - any ideas ????
