In the octet that you want
1) have the network portion be even if you want to deny or permit even networks. have the network portion be odd if you want to permit or deny odd networks.
2) use a mask of 254 for that octet
i.e. for specifying even in the 3rd octet
access-list 1 permit 172.172.64.0 0.0.254.255 (the 64 can be any even number)
i.e. for specifying odd in the 3rd octet
access-list 1 permit 172.172.65.0 0.0.254.255 (the 65 can be any odd number)

Subject: Calculating ACLs to allow even networks routes - distribute
list
Can someone provide the method please to calculate the minimum ACL lines to say allow even network routes as opposed to odd network routes in a distribute list please. I would like to spend some time this week working some of these situations out. I assume you need to work out the wildcard mask you need.
Thanks
