[nsp] BGP best route problem

[Aki Anttila]

Hi!

It seems that you cannot get "show ipv6 route" in user exec mode. Anyhow, 
my first suggestion would be that the next-hop is not reachable all the 
time. Could you paste more of the configs? I would be interested to know, 
by what means you get the next-hop address and whether it is a loopback or 
physical address?
