I don't think I understand how to trouble shoot MPLS still. Anybody have any good links on troubleshooting end to end MPLS. I am just not getting it. I am not sure where this is broken.

To simplify this I usually run OSPF or IS-IS in the core and turn on "ldp autoconfig" under the routing process for the LSR"s. This will enable LDP on all your interfaces automagically so you don't have to do it manually. Of course you do what your lab tells you but if you are just playing around this saves lot's of time :) router isis mpls ldp autoconfig or router ospf 1 mpls ldp autoconfig If you have a topology and configs I would be more than happy to lab this up.

Check 'sh MPLS forwarding' and 'sh MPLS ldp ne', etc. Verify the LSP. Bob -- Sent from my iPhone, please excuse any typos.
