OSPF Distribute-List Filtering

Hi Rene,

Really enjoying the OSPF lessons! Just one query, the first output is what you had in the lesson and am just wondering why you chose the network statement for the loopback 0 as 1.1.1.0 0.0.0.255 area 0, instead of 1.1.1.1 0.0.0.0 area 0, as in the second output?

R1#show running-config | section ospf
router ospf 1
 <strong>network 1.1.1.0 0.0.0.255 area 0</strong>
 network 192.168.12.0 0.0.0.255 area 0
 
R1#show running-config | section ospf
router ospf 1
 network 1.1.1.1 0.0.0.0 area 0
 network 192.168.12.0 0.0.0.255 area 0
 network 192.168.12.0 0.0.0.255 area 0

Regards,
