5 Assign an IP address to the interface in INTERFACE mode.
ip address ip-address/mask
6 Enable OSPFv2 on an interface in INTERFACE mode.
ip ospf process-id area area-id
• process-id—Enter the OSPFv2 process ID for a specic OSPF process from 1 to 65535.
• area-id—Enter the OSPFv2 area ID as an IP address (A.B.C.D) or number from 1 to 65535.
Enable OSPFv2 conguration

Assign router identier
For managing and troubleshooting purposes, you can assign a router ID for the OSPFv2 process. Use the router’s IP address as the router
ID.
• Assign the router ID for the OSPFv2 process in ROUTER-OSPF mode
router-id ip-address
Assign router ID
OS10(config)# router ospf 10
OS10(conf-router-ospf-10)# router-id 10.10.1.5

Stub areas
Type 5 LSAs are not ooded into stub areas. The ABR advertises a default route into the stub area to which it is attached. Stub area routers
use the default route to reach external destinations.
