Internet Router

[Gerry6467]

Just started a new position and am getting the ropes. What I am currently working on is a reconfig to the Internet router on an extended access-list. I do not want to have to rebuilt the ACL. On line 140 of my ACL I have the following:

permit ip host xxx.xxx.xxx.xxx host yyy.yyy.yy.yyy log-input

I need to know what the best method or how to change the xxx.xxx.xxx.xxx IP without having to rebuild the ACL. Could someone help me out? Just need to change that one IP and I am good to go.

Appreciate the help.

If you have IOS version 12.3 or 12.4, each ACL entry will have a sequence number. You can actually delete and re-write an individual line without having to recreate the ACL.

The following URL explains more about it

What the URL doesn't really touch upon is if you want to delete a superceded entry, you just do 'no 20' for instance to delete line 20 in ACL (assuming you are in extended or standard ACL config mode)
