Hi to all of you,

I am using quagga 1.2.1 on a freebsd (10.0) as provided from an already
compiled packaged. We are using quagga in the university lab to teach
routing protocols.

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..
