We are attempting to configure an ACL on a 2600 series router.
The network that we wish to permit access from is x.x.x.128 (255.255.255.128).
In the extended ACL we are using the following syntax
access-list 101 permit ip x.x.x.128 0.0.0.128 any
The router accepts this, but when you subsequently do a show access-list 101, it shows the following
access-list 101 permit ip x.x.x.0 0.0.0.128 any
which relates to a totally different subnet (which in this case is the destination network).
This seems to happen unless 0 or 255 is used in the wildcard mask.
Has anyone encountered this/ any suggestions? is this just a display issue on the show command?
