Configuring OSPF
Basic Functions
You need to enable OSPF, specify an interface and area ID first before performing
other tasks.
Prerequisites Before configuring OSPF, you have configured the link layer protocol, and IP
addresses for interfaces, making neighboring nodes accessible with each other at
the network layer.
Configuration Procedure To ensure OSPF stability, you need to decide on router IDs and configure them
manually. Any two routers in an AS must have different IDs. In practice, the ID of a
router is the IP address of one of its interfaces.
The system supports OSPF multi-process. When a router runs multiple OSPF
processes, you need to specify an ID for each process, which takes effect locally
and has no interference on packet exchange between routers. Therefore, two
routers having different process IDs can exchange packets.
