5.7.5.2.3 Configuring Global Settings for OSPF

To implement OSPF for a large network, you must first organize the network into logical areas to limit the number of OSPF routers that actively exchange Link State Advertisements (LSAs). You can then define an OSPF interface by assigning an IP interface configured on this switch to one of these groups. This OSPF interface will send and receive OSPF traffic to neighboring OSPF routers. You can further optimize the exchange of OSPF traffic by specifying an area range that covers a large number of subnetwork addresses. This is an important technique for limiting the amount of traffic exchanged between Area Border Routers (ABRs). And finally, you must specify a virtual link to any OSPF area that is not physically attached to the OSPF backbone. Virtual links can also be used to provide a redundant link between contiguous areas to prevent areas from being partitioned, or to merge backbone areas.

The OSPF global configuration consist a configuration page and a few sub-menu.

Parameter

Default

Description

Router ID

STATIC INTF Defines how the Router ID is determined: There are three options:

Selection

 

STATIC: User can manual configure the Router ID.

 

 

 

 

STATIC INTF: The VLAN 1 IP address will be used as Router ID

 

 

ACTIVE INTF: The first active interface will be used as Router ID

Router ID

VLAN 1 IP

A 32-bit number assigned to each router running the OSPF protocol.

 

 

This number uniquely identifies the router within an Autonomous

 

 

System.
