[j-nsp] Sending iBGP prefixes to another iBGP neighbour

let me fix my errors: I mean tot say L3VPN not L2 ;)

___________________________

If you put the Linux session into a VRF on the MX104, then run *L3VPN* between the MX104 and MX80, (may have to enable the independent-domain knob in the vrf), you can solve it that way too.. 

however the egress interface on the MX80 also needs to be in the VRF.

Topology:

iBGP(Linux) -> (VRF)MX104 -> L3VPN/iBGP/MPLS -> MX80(VRF) -> eBGP

- CK.
