Task Remarks

Configuring BFD for OSPF Optional

Enabling OSPF

Enable OSPF before you perform other OSPF configuration tasks.

Configuration prerequisites

Configure the link layer protocol and IP addresses for interfaces to ensure IP connectivity between

neighboring nodes.

Configuration guidelines

Complete the following tasks to enable an interface to run an OSPF process in an area:

• Enable the OSPF process

• Create the area for the OSPF process

• Add the network segment where the interface resides to the area. The OSPF process advertises the

direct route of the interface.

• Specify a router ID, the unique identifier of the router in the AS.

Following is additional information about router IDs:

• You can specify a router ID when you create an OSPF process. Any two routers in an AS must have

different router IDs. A typical practice is to specify the IP address of an interface as the router ID.

• If you specify no router ID when creating the OSPF process, the global router ID is used. HP

recommends specifying a router ID when you create the OSPF process.

OSPF can run multiple processes and supports VPNs.

• To run multiple OSPF processes, you must specify an ID for each process. The process IDs take effect

locally and has no influence on packet exchange between routers. Two routers with different

process IDs can exchange packets.

• VPN support enables an OSPF process to run in a specified VPN.

Configuration procedure

To enable OSPF:

Ste

Command

Remarks

1. Enter system view.

system-view N/A

2. Configure a global router

ID.

router id router-id

Optional.

Not configured by default.

If no global router ID is configured, the

highest loopback interface IP address, if

any, is used as the router ID. If no loopback

interface IP address is available, the highest

physical interface IP address is used,

regardless of the interface status.

3. Enable an OSPF process

and enter OSPF view.
