[j-nsp] Resolving BGP routes using LDP tunnels

[Armin Arh]

Hi,

this should work.
Of course you should have an IGP configured like OSPF or ISIS.
Then LDP computes labels for all IGP routes, hop by hop.

R2 receives then a MPLS packet from R3 with a label
that points towards R1. R2 then forwards it
to R1 without looking into the IP header.

bye,
	Armin
