[quagga-users 14689] IPv6 BGP routes from a directly connected peer are not accepted in the routing table

Hi to all of you,

Apologies for cross-posting already to the dev list.

I am using quagga 1.2.1 on a freebsd (10.3) as provided from an already 
compiled packaged. In a simple set up of two connected routers where I 
setup a direct external bgp peering, the routes are exchanged but are 
not established in the routing table as their bgp_nhop is reported as 
inaccesible although it is received from a connected interface.

See the attached image. The configuration of two routers follows..

Do you believe there is an error in the configuration ? or is it a bug ?

Cheers,
