Configuration Procedure - HP 3600 v2 series Configuration Manual

Configuration procedure

To enable OSPF on a router, create an OSPF process and specify areas with which the process is
associated, and the network segments contained in each area. If an interface's IP address resides on a
network segment of an area, the interface belongs to the area and is enabled with OSPF, and OSPF
advertises the direct route of the interface.
To run OSPF, a router must have a router ID, which is the unique identifier of the router in the AS.
Following is additional information about router IDs:
• You can specify a router ID when creating the OSPF process. Any two routers in an AS must have
different router IDs. In practice, the ID of a router is the IP address of one of its interfaces.
If you specify no router ID when creating the OSPF process, the global router ID is used. HP
•
recommends you to specify a router ID when you create the OSPF process.
OSPF can run multiple processes and supports VPNs as follows:
When a router runs multiple OSPF processes, specify a router ID for each process, which takes
•
effect locally and has no influence on packet exchange between routers. Two routers having
different process IDs can exchange packets.
• OSPF support for VPNs enables an OSPF process to run in a specified VPN.
Follow these steps to enable OSPF:
To do...
Enter system view
Configure a global router ID
Enable an OSPF process and
enter OSPF view
Configure a description for the
OSPF process
Configure an OSPF area and
enter OSPF area view
Configure a description for the
area
Specify a network to enable
OSPF on the interface attached
to the network
Use the command...

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.
