We are running a network, where we have border, core and access as cisco suggest.
We are using a simple access-list on Core router to permit our IP?s. Like if traffic is from 10.10.10.0 255.255.225.0 permit rest deny. Well, whatever I have permitted it?s running fine. Whenever I try to permit another any IP or Network, latency/delay increase in 1000s ms
For example I want to add another network like 132.xxx.xxx.x 255.255.255.0 and. I?m pretty sure there is no traffic from that source IP or Network which belongs to this class, my network latency increase upto 1000s ms. When I remove that entry from the access list, it take 5 to 10 seconds and become normal.
Have you guys faced such a problem?
