[c-nsp] BGP Route Selection

[Gregory Boehnlein]

Thanks to everyone that replied.. indeed, I typoed on my route-map..

core1#show route-map as-3356-incoming
route-map as-3356-incoming, permit, sequence 5
  Match clauses:
    as-path (as-path filter): 99 
  Set clauses:
    local-preference 150
  Policy routing matches: 0 packets, 0 bytes
route-map as-3356-incoming, permit, sequence 10
  Match clauses:
  Set clauses:
    metric 1000
    local-preference 100
  Policy routing matches: 0 packets, 0 bytes

That the as-path filter should be 97, not 99.
