The BGP extended ACL works differently from the regular extended ACL. Here is how it goes.
In the access list that you gave as an example : access-list 101 permit ip 10.6.144.48 0.0.0.8 255.255.255.240 0.0.0.8 a .10.6.144.48 is the source network b. 0.0.0.8 is the wild card mask asssociated with the source network. c. 255.255.255.240 is the subnet mask that is used for the network 10.6.144.48 d. 0.0.0.8 is the wild card mask just for the subnet mask 255.255.255.240 Note : Both meanings of c and d will be different for the regular ACLs. Hope this helps. The application for this type of ACL is to permit/deny all but one type of subnet while still denying/permitting other subnets in the entire class.
