Can anyone please clarify how the 'wildcard mask' in the 'network' command works with OSPF.
I am confused by the answer given to question 7 at the start of Chapter 6 of the Cisco Press ICND Exam Cert Guide book by Wendell Odom.
This question asks if the command :-
network 10.0.0.0 0.255.255.0 area 0
will match interface IP addresses 10.1.1.1, 10.1.100.1, and 10.1.120.1.
What is the right answer here ?
As I understand it 0.255.255.0 means first and last octets must match 10.0.0.0, so does this mean the IP address themselves must match this, or can it be sufficient that the network in which these IP addresses reside match it ? For example all the above IP addresses are in 10.0.0.0, but does this mean they match in the above command ?
