Hi all,

I am still having problems with coming up with generic wildcard mask for
blocking odd or even networks, my example:

allow only even networks from 198.5.51.0/24 to 198.5.59.0/24

I tried the following:

access-list 10 permit 198.5.1.0 0.0.254.255 which should permit odd (no
success)

access-list 10 permit 198.5.0.0 0.0.254.255 which should permit even (no
success)

access-list 10 permit 0.0.0.0 255.255.254.255 should permit even (IT WORKS)

The way I see it, the concept is just the same in all the above examples,
why last one works and not the others.

Appreciate your input

Ya
