Hi All,
Need some help on ACL calculation. This is general ACL filtering scenario. I'm just practicing on ACL filtering especially on the non-continuous wildcards. i've injected this to my test router but i don't seem to get the logic why it's this wildcard. can somebody enlighten me on this? I know 0 in the wildcard are care bits and 1 don't care, just the opposite of a subnet mask. Example Scenario: I get this networks from a backbone router: network 10.10.10.0 network 10.10.11.0 network 10.10.12.0 network 10.10.13.0 network 10.10.14.0 network 10.10.15.0 network 10.10.16.0 I want to filter on the third octet and allow only 10, 13, 14 to come in been playing with various values on the wildcard, and the working value is 0.0.4.0 , WHY???? Kind Regards, Antonio
