Thanks for info.

You are using single-hop EBGP, therefore next hop is not resolved
through a routing table, but directly through interface table,
but still it should take into account VRF protocol specified
by the BGP protocol.

I guess setting 'gateway recursive' BGP option would fix the issue,
but that is just workaround, it should work even without it.

Could you try compile and run current 'int-new' branch from GIT?
It has plenty of fixes related to neighbor cache, which may be
related.

Could you also show your config for bgp_vrf01_ixia1 protocol?
That was not in the config from original post.

It may be useful to know if your established BGP sessions were incoming
or outgoing. Could you check that using netstat/ss?

Also, what is your kernel versions? Older kernels have limited support
for VRF, but not sure if that is related.
