Hi Alessandro,

Yes sure.

You can define FEC entrys for different LSPs. Fec entrys take the
dest-address and flowid as identifyer for the packets that have to put on
the LSP. So the source router is not relevant only the destination and
flowid. I think the real MPLS RFC describe a more sofisticated method but
i think ns2 do not support that. Here an example:

set lsr [eval $node get-module "MPLS"]
$lsr bind-flow-erlsp [$dest node-addr] $flowid $lspid

first you have to define an LSP with the same lspid.
