[c-nsp] OSPF fast hellos

[Ben Steele]

Because I couldn't see bfd support for 3750's, best it can do is UDLD,
otherwise that would be my preferred method.

Are you advising against fast hello's? Have you seen many issues with people
using them?

Why don't you use BFD instead. It's designed with something called
pseudo preemption from an OS scheduler perspective that helps
reduce false positives and the fact that BFD frames are handled
under interrupt and not process scheduled for rx/tx.
