DYNAMIC ROUTING USING OSPF

X. DESCRIPTION (MATERI)

1.    Objective

Objective: Configure OSPF on the network

•    Understand the concepts of OSPF routing protocol

•    Configure dynamie routing protocol using OSPF

•    At last, u know that networking is not easy, not just cabling and ip address and all device will operate on ur mind. Networking need skill and morę skills, need to study hard.

2.    Background Reading

Go to the Cisco website, or use the Cisco Sybex publication, and read about dynamie routing with OSPF. You can read following tutorial to understand OSPF, we have downloaded that from Cisco website.

OSPF configuration includes only a few required steps, but it has many optional steps. After an OSPF design has been chosen—a task that may be complex in larger IP intemetworks—the configuration may be as simple as enabling OSPF on each router interface and placing that interface in the correct OSPF area.

This section shows a simple configuration example of a single-area OSPF internetwork. For reference, the following list outlines the configuration steps as well as a brief reference to the reąuired commands:

Step 6

Enter OSPF configuration modę for a particular OSPF process using the router ospf process-id global command.

Configure the OSPF router ID by:

a Configuring the router-id id-value router subcommand.

h Configuring an IP address on a loopback interface. Configure one or morę network ip-address wildcard-m ask area area-id router subcommands, with any matched interfaces being added to the listed area.

Change the interface Hello and Dead intervals using the ip ospf hello-interval time and ip ospf dead-interval time interface subcommands.

Impact routing choices by tuning interface costs as follows:

c. Configure costs directly using the ip ospf cost value interface subcommand.

d. Change interface bandwidths using the bandwidth value interface subcommand.

e. Change the numerator in the formula to calculate the cost based on the interface bandwidth, using the auto-cost reference-bandwidth value router subcommand.
