4.5.6.1.5 Configuring OSPF

Open Shortest Path First is more suited for large area networks which experience frequent changes in

the links. It also allows for subnets. This protocol actively tests the status of each link to its neighbors to

generate a shortest path tree, and builds a routing table based on this information. OSPF then utilizes IP

multicast to propagate routing information. A separate routing area scheme is also used to further reduce

the amount of routing traffic. You can use the following menu to specify the area identifier, or other key

routing parameters as described in the following table.

Parameter Default

Description

Area ID

*1

0.0.0.0

A 32-bit integer uniquely identifying an OSPF protocol broadcast area

This identifier can be in the form of an IP address or integer. Each

port on the switch can be configured to represent one OSPF area.

You must first specify OSPF areas for global access in the Area ID

Configuration menu, before they can be used for a specific IP

interface.

ID 0.0.0.0 is used for the OSPF backbone.

Router Priority

1

The priority used when selecting the designated router and

designated backup router.

Range: 0-255; Disable election: 0

Interface Cost
