Yep, we started seeing this right around 12:20pm MST. We saw it from a
customer's rapidly-flapping BGP peer. We told them to configure bgp
maxas-limit, but apparently CRS1s don't have that command.
Anybody have a handy route-map that will deny anything with a as-path
longer than say 15-20? ;-)
Cheers,
Randal
