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

1 Log into User EXEC mode.

5530-24TFD> enable

2 Log 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.

Enable IP routing globally.

5530-24TFD(config)# ip routing

Enable OSPF globally.

5530-24TFD(config)# router ospf en

Log 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.

Create a port type VLAN as VLAN number 35 in spanning tree

protocol group 1.

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

Log into the Interface Conﬁguration mode for VLAN 35.

5530-24TFD(config)# interface vlan 35

Enable IP routing on VLAN 35.

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