[c-nsp] BFD on customer-facing interfaces - experiences

[Eric Louie]

We're looking for any ISPs who have experience with BFD configured on
customer-facing interfaces (OSPF or BGP).  Was it reliable?  Did it cause
too many false positives for down routing sessions?  What about
re-establishing the routing protocol when BGD recovers?  Did you have issue
with root cause analysis when the sessions dropped (as in explaining to the
customers why their routing session went down or flapped)?

thanks, Eric
