4.3.2 Enabling OSPF

Create an OSPF process and specify a router ID to enable OSPF. After enabling OSPF, specify
an interface on which the OSPF protocol is running and the area to which the interface belongs.
After that, routes can be discovered and calculated in the AS.
Context
Before running OSPF on the switch, specify a router ID for the switch. The router ID is a 32-
bit unsigned integer, which identifies the switch in the AS. To ensure OSPF stability, manually
set the router ID of each switch during network planning.
This causes the link state database (LSDB) to unexpectedly grow. OSPF resolves this problem
by partitioning an AS into different areas. The area is regarded as a logical group and each group
is identified by an area ID. At the border of an area resides the switch instead of a link. A network
segment (or a link) belongs to only one area. The area to which each OSPF interface belongs
must be specified.
Procedure
Step 1 Run:

The system view is displayed.
Step 2 Run:
ospf [ process-id | router-id router-id | vpn-instance vpn-instance-name ]
The OSPF process is started, and the OSPF view is displayed.
l process-id specifies the process ID and the process-id value is 1 by default. The S6700

system automatically selects the IP address of an interface as the router ID. Ensure that each
router ID is unique in the AS when manually configuring router IDs. The IP address of an
interface on the S6700 is generally configured as the router ID of the S6700.
