[c-nsp] Granularity for BFD in CoPP policy

[Drew Weaver]

Howdy!

I have noticed that if I put:

permit udp any any eq 3784
permit udp any any eq 3785

Into a CoPP policy, this makes BFD function between two systems.

If I try to get specific and use the source and destination addresses of the two systems BFD flaps wildly.

I would assume, most likely foolishly that the NeighAddr listed in 'sh bfd nei' would be the source IP of the BFD packets but it appears that I am mistaken.

Any ideas?
