RE: [nsp] [nsp]Wanna ask about BGP on cisco

The router is receiving a next-hop of via bgp,
however it does not have a valid IGP route to this IP
address. Make sure is in your routing
table. However that is probably not what the real problem looks like the peer is giving this
address as next-hop, when it probably wants to advertise
a non-rfc1918 address.

Be careful if you see rfc1918 together with BGP...
