Open Shortest Path First (OSPF) initial configuration

This section contains the steps necessary for the initial configuration of OSPF on the switch. More advanced configuration examples can be found in the "IP routing configuration examples" (page 120)section.

Basic OSPF configuration

A basic OSPF configuration will learn OSPF routes from other OSPF devices and propagate routes to other OSPF devices. The following procedure outlines the creation of a basic OSPF configuration:

Step Action

1Log into User EXEC mode.

5530-24TFD> enable

2Log into Global Configuration mode.

5530-24TFD# config terminal

The switch will respond with the following line:

Enter configuration commands, one per line. End with CNTL/Z.

3Enable IP routing globally.

5530-24TFD(config)# ip routing

4Enable OSPF globally.

5530-24TFD(config)# router ospf en

5Log into the OSPF router configuration mode. It is not necessary to make any changes at this time but entering the router configuration mode is a good way to verify that the mode has been activated.

5530-24TFD(config)# router ospf

Note: The remainder of this procedure refers to VLAN 35. Although VLAN 35 is used for this example, any port type VLAN could be used.

6Create a port type VLAN as VLAN number 35 in spanning tree protocol group 1.

5530-24TFD(config)# vlan create 35 type port 1

7Log into the Interface Configuration mode for VLAN 35.

5530-24TFD(config)# interface vlan 35

8Enable IP routing on VLAN 35.

5530-24TFD(config-if)# ip routing
