[c-nsp] Cisco 7204 VXR strange behavior

[Rodney Dunn]

How do you know the traffic was going to Null0?

Very unlikely the router just decided to dump traffic to Null0
for no reason. I've never heard of that.

Do you have 'sh ip route' 'sh ip cef' debug ip policy, etc..
to prove it and what the config looked like at the time?
