[nsp] whats bgp scan all about

[Ilker TEMIR]

Well, ICMP is another low priority process on the router. So ICMP traffic
*destined to* router could be affected (not the traffic flowing *through*
the router)

There is not too much you can do about it. Just check if there is route
flapping etc as it may affect the time bgp scanner takes.
