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 need to configure IP addresses for interfaces, making neighboring nodes
accessible with each other at the network layer.
Configuration Procedure
z
Configure a Router ID
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.
z
Enable an OSPF process
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 influence on packet exchange
between routers. Therefore, two routers having different process IDs can exchange packets.
z
Configure an area and specify networks in the area
The configurations for routers in an area are performed on the area basis. Wrong configurations may
cause communication failures, even routing information block or routing loops between neighboring
routers.
Follow these steps to configure OSPF basic functions:
