Hi. I have been practicing OSPF but suddenly I'm a bit confused about how to calculate the following OSPF wildmask.
Router NETWORK Fast e 0 serial 0 Loopback
R_1 192.168.1.0 192.168.1.129/26 192.168.1.1/30 192.168.31.11./32
R_2 192.168.1.0 192.168.0.1/24 192.168.1.2/30 192.168.31.22/32
No matter what i try, i always end up with the following results:-
R_1 network 192.168.1.0 0.0.0.3 area 0
R_2 network 192.168.1.0 0.0.0.3 area 0
network 192.168.0.0 0.0.0.255 area 0
When i checked with my instructor, the answer on his manual showed a different thing. Could his manual be wrong?

The easiest thing is to use the exact link address with a wildmask of 0.0.0.0:
R_1 network 192.168.1.129 0.0.0.0 area 0
R_1 network 192.168.1.1 0.0.0.0 area 0
R_1 network 192.168.31.11 0.0.0.0 area 0
R_2 network 192.168.0.1 0.0.0.0 area 0
R_2 network 192.168.1.2 0.0.0.0 area 0
R_2 network 192.168.31.22 0.0.0.0 area 0
cheers!
