F. None of the above...
Because of bit boundaries though, you can't summarize quite so nicely.
access-list 6 permit 192.168.123.0 0.0.0.255
access-list 6 permit 192.168.124.0 0.0.3.255
That will cover 123, 124, 125, 126 and 127. The implicit deny will catch
128 and 129....
Hope that helps.
Scott

Suppose that the backbone is advertising the following routes:
192.168.123.0/24
192.168.124.0/24
192.168.125.0/24
192.168.126.0/24
192.168.127.0/24
192.168.128.0/24
192.168.129.0/24
I need to filter .128 and .129 and pass every thing else. which of the
following access list is correct
access-list 1 permit 192.168.123.0 0.0.7.255 or
access-list 2 permit 192.168.124.0 0.0.7.255 or
access-list 3 permit 192.168.125.0 0.0.7.255 or
access-list 4 permit 192.168.126.0 0.0.7.255 or
access-list 5 permit 192.168.127.0 0.0.7.255
