*access-list 102 permit ip 192.168.10.0 0.0.0.255 255.255.255.0 0.0.0.255* This access-list permits all the subnets of 192.168.10.0/24. In other words, it will allow 192.168.10.0/24, 192.168.10.0/25, 192.168.10.128/25, and so forth: any of the 192.168.10.*x* networks with a mask that ranges from 24 to 32.
This notes is taken from cisco pages.As far as I know for bgp filtering estended access list used for exact mask length . What I was expected this access list to fileter only 192.168.10.0/24 and not ant other prefix. and what is the diffrence access-list 1 perint 192.168.10.0 0.0.0.0.255 and above acess lsit if both of thme are allowing /25,/26 prefixes?
