OSPF Quick Steps

Configuring OSPF

page 1-4

OmniSwitch 6600 Family Advanced Routing Configuration Guide

The followings steps are designed to show the user the necessary set of commands for setting up a router 
to use OSPF:

1 Create a VLAN using the 

 command. For example:

-> vlan 5

-> vlan 5 enable

2 Assign a router IP address and subnet mask to the VLAN using the 

 command. For exam-

ple:

-> ip interface vlan-5 vlan 5 address 120.1.4.1 mask 255.0.0.0

3 Assign a port to the created VLANs using the vlan command. For example:

-> vlan 5 port default 2/1

Note. The port will be statically assigned to the VLAN, as a VLAN must have a physical port assigned to 
it in order for the router port to function. However, the router could be set up in such a way that mobile 
ports are dynamically assigned to VLANs using VLAN rules. See the chapter titled “Defining VLAN 
Rules” in the OmniSwitch 6600 Family Network Configuration Guide.

4 Assign a router ID to the router using the 

 command. For example:

-> ip router router-id 1.1.1.1

5 Load and enable OSPF using the 

 and the 

 commands. For example:

-> ip load ospf

-> ip ospf status enable

6 Create a backbone to connect this router to others, and an area for the router’s traffic, using the 

 command. (Backbones are always labeled area 0.0.0.0.) For example:

-> ip ospf area 0.0.0.0

-> ip ospf area 0.0.0.1

7 Enable the backbone and area using the 

 command. For example:

-> ip ospf area 0.0.0.0 status enable

-> ip ospf area 0.0.0.1 status enable

8 Create an OSPF interface for each VLAN created in Step 1, using the 

 command. The 

OSPF interface should use the same IP address or interface name used for the VLAN router IP created in 
Step 2. For example:

-> ip ospf interface 120.1.4.1

or

-> ip ospf interface vlan-5
