The network-number identifies the network using OSPF. The mask tells which bits to
use from the network-number, and the area-id is used for determining areas in an OSPF
configuration. For example:
Router(config-router)#network 10.12.0.4 255.255.255.252 area 0
Area 0 is so called backbone network.
2.2.2 Router ID
Router ID is the tie-breaker for OSPF path selection. The path selection process uses a
variety of metrics to select a route. If all other metrics (accessibility, administrative
weight, local preference, etc.) are equal, OSPF determines the router ID using the
following priority:
1. Use the address configured by the ospf router-id command
2. Use the address of the loopback 0 interface
3. Use the highest IP address of any interface
4. If no interface exists, set the router-ID to 0.0.0.0
