[rbak-nsp] IPv6 BGP - inter-context

Hi everyone,

I have working multiple context configuration with some context being
routed with BGP.
So called "master-ctx" is connected to world, has public BGP peerings
and so. In turn "peer-ctx" is only connected to master with single BGP
session using loopback IPv4 addresses.

This workswell for IPv4(*) and recently I've tried to introduce IPv6 on
this - without success.
First it is not possible to do something like: "ip route 10.0.0.2/32
context peer-ctx"for ipv6, as "ipv6 route X:X::/X ..." does not support
context keyword.

MBGP was another option I've tested. IPv4 & IPv6 unicast routes are
received, but they're not importedas no link-local address seems to active.
On both sides next-hop is: 6dc4:7076:5b:6::5:607:1...

Any clues?


(*) Only problem/feature is that when doing trace from "peer-ctx" side
next-hop seems to be taken randomly from "master-ctx" defined interfaces...
