Hi Friends, Manoj here .. i need your advice to help me understand the below two ACLs that i found in one of my routers
permit ip host 0.0.0.0 host 255.255.255.255
permit ip host 255.255.255.255 host 0.0.0.0
Looking forward for your answers. Thx in advance ..
The source would be 0.0.0.0 since the machine is actually requesting an IP and does not have any IP at that time.
The Reply would never have the source as a broadcast and destination 0.0.0.0
DHCP replies would have the source IP of the DHCP server and the destiantion would either be a broadcast or a unicast (if some DHCP relay agent is used)
So i think the 2 nd ACL is a false config (do u see any matches)
To reset the counters you can use the following command
Clear access-list counters
HTH, rate if it does
