Hello, I wonder if anyone can tell me what are the possible causes for input packet hits on interface Null0? (I'm not talking about output packet hits caused by blackhole routing). I first noticed this on a 3800 VPN router, but I've now noticed it on...
Hello,I have noticed that I am getting a large amount of packets input on my 3825 VPN router when I do a 'show int null0'.I understand the normal reasons for packets going out of null0 (summarization, desired black holing etc) but why would null0 be ...
