[c-nsp] re-advertising eBGP learned prefixes

[Andrey Koklin]

I need to re-advertise some eBGP-learned routes to another eBGP peer, like:

ClientA---> ASX---R3-AS2---> R1-AS1--(ibgp)--R2-AS1---> R4-AS3

BGP advertises only prefixes originating in the same AS.
But we need to propagate some prefixes further to another eBGP-peer.

Do there exist a solution for such a thing?
