Re: Multi-hop MP-eBGP connection

Is the path from R7 to R9's loopback totally label switched? Try doing
a traceroute and check every hop if the label matches.
If routing information is correct, it's almost always an issue with
your end-to-end LSP (since R7 and R9 might be able to ping each other,
but not through MPLS).
