Please forgive me for my lack of knowledge. I am new to cisco IOS commands. I am attempting to study for CCNA while I have a need to manage 2600 series routers. Very confusing when trying to learn commands.
I have 2 questions if you don't mind:
1. I am attempting to block specific IP addresses on eth0 in the wake of the lastest w32.sobig virus to keep my e-mail server from crashing and to keep the clutter out of my users mailboxes. What are the commands to simply create a new access-list and apply it to a specific eth port? Or, if easier, how could I add these ip addresses to existing ACL?
2. Where might I find a complete list of commands for the 2651 that I can reference when in need, such as today?
An interface can only have two access-lists; one for input and one for output. If there is already an access list on the interface for the direction you want then you must add your new statements to it but its not a simple subject.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
