[nsp] policy routing / CEF-IP-POLICY: fib for address10.209.254.254 is with flag 0

[Kinczli Zoltán]

Hello,

  yes..., sorry i was not accurate enough. All i wrote applies to non-adjacent next-hops
as you correctly pointed out

  BGP and CEF have their own, periodic checker/updater, PBR hasn't. 

  I hope the rest is correct... at least my signature is ;)

Yes and no.  

Yes, this is used for BGP next-hop manipulation, too.

But no, it's not used *exclusively* for that - "set ip next-hop" works fine
if the next-hop is directly adjacent.  (I tried that).

The CEF adjacency is there, so at least with CEF, there is not much that
needs to be done.  It's just basic CEF forwarding... - not different from
a BGP route with a non-adjacent next-hop (which works well).

But thanks for your comment, it means "yes, this is a known issue".
