OSPF Network statement

All,

I have 5 /24 networks and want to represent them by a single OSPF network
statement.

150.1.7.7
150.1.37.7
150.1.67.7
150.1.79.7
150.1.72.7
!
router ospf 1
 network 150.1.1.7 0.0.110.0 <-- this is like access-list right?
% OSPF: Invalid address/mask combination (discontiguous mask)
!

If I remember from one of the reading from IE's Q&A section

To find the most specific address and
wildcard pair that will

match two addresses, A and B, we use the gates AND and XOR. The address

we will check in the access-list is A AND B. The wildcard used to check

in this list will be A XOR B.

access-list 1 permit [address_to_check] [wildcard_used_to_check]
