Do you have any other interfaces or loopbacks that might be getting used for the LDP connection that aren't part of the routing domain?
I labbed this up quick (since I haven't set up LDP in months!) and I happened to have a tunnel interface on the test router that I was using which is what LDP tried to initiate the LDP session from. I could resolve that by adding all interfaces to a dynamic routing protocol like OSPF, or specifying the LDP router-id to be an interface that I had reachability between, or by forcing the MPLS connection to use the interface IPs with: int fa0/0 mpls ldp discovery transport-address interface Check 'show mpls ldp discovery' to see what address is being used for the LDP sessions and see if it's reachable. Really, you want to set the LDP router-id to something reliable like a loopback, and make sure you have /32 routes between those LDP RIDs. IIRC, without that, you may get LDP up but you'll have other various issues.
