10.2Open Shortest Path First (OSPF)

Open shortest path first (OSPF) is an interior gateway protocol developed by the OSPF working group of Internet Engineering Task Force (IETF). OSPF designed for IP network supports IP subnetting and marks on information from exterior network. Moreover, it sup- ports packet authorization and transmits/receives routing information through IP multicast. It is most convenient to operate OSPF on layered network.

OSPF is the most compatible routing protocol in layer network environment. The first set- ting in OSPF network is planning network organized with router and configures border router faced with multiple section.

After that, sets up the basic configuration for OSPF router operation and assigns interface to Area. To make compatible OSPF router configuration for user environment, each router configuration must be accorded by verification.

This section provides configurations for OSPF routing protocol. Lists are as follows.

•Enabling OSPF

•ABR Type Configuration

•Compatibility Support

10.2.1Enabling OSPF

To use OSPF routing protocol, it must be activated as other routing protocols. After activa- tion, configures network address and ID which is operated by OSPF.

The following command shows steps of activating OSPF.
