How do I construct the access-list to match prefix/prefix-length? Not only prefix. I am reading the CCNP routing study guide (642-802) and autor says by implementing an extended ACL (source address should match the prefix and destination address should match the prefix length).

But offset-list EIGRP router command do not allow extended access-list in parameters!!!!


I am testing using GNS3 with IOS Version 12.4(17a).

I wonder about the context of the original statement about using an extended access list. Is it possible that it was talking about doing this with BGP? It does work with BGP to use an extended access list and the first address and mask define the prefix and the second address and mask define the prefix length.
