[rbak-nsp] MPLS Forwarding

[Ali Norouzi]

Dear All,

I have an issue with MPLS Forwarding of Redback SE100. This SE100 acts as
router and terminates some a wireless users. I want to send the IP traffic
to the core with MPLS tag. SE100 and core router are LDP neighbor over a
directly connected link. MPLS is enabled on both interfaces. When I get "*show
ip route*" results from SE100 it shows a strange results for that
destination that I want to send traffic towards them with MPLS tag. That
result is: *"Active LSP path ineligible for fib, only used for recursion"*.
