The 1st will working if you are filtering packets, the 2nd one will be
used when you dealing with routes

Subject: Question about Prefix filtering
Hi guys,
For example, there are following network:
192.168.1.0
192.168.2.0
192.168.3.0
192.168.4.0
192.168.5.0
192.168.6.0
192.168.7.0
192.168.8.0
The question asks me to filter the odd routes, I think there are two
working configs:
1.
access-list 1 deny 192.168.1.0 0.0.254.255
access-list 1 permit any
2.
access-list 1 deny 192.168.1.0 0.0.254.0
access-list 1 permit any
Both of the configs will work well but which one is better and more
correct?
Thanks.
