Enabling OSPF

Enable OSPF before you perform other OSPF configuration tasks.

Configuration prerequisites

Configure the link layer protocol and IP addresses for interfaces so that neighboring nodes can
communicate with each other.

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.
Hewlett Packard Enterprise 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. For more information about
VPN, see MPLS Configuration Guide.
