Hi,
“mpls traceroute” & “show mpls forwarding” will never let you down, 99% of the cases an end-to-end LSP is missing (some router is not advertising labels or not mapping BGP to LDP labels properly).
Check if PE loopbacks/RIDs have labels allocated and advertised hop by hop as follows:
In inter-AS scenarios you need to be checking two hierarchies though:
1)
BGP Label mappings for PE-->ASBR-->ASBR-->PE…
2)
IP LDP Label mappings PE-->P-->P-->ASBR in each AS
