Configuring OSPF

OSPF Application Example

OmniSwitch 6600 Family Advanced Routing Configuration Guide

page 1-33

The first step is to create the VLANs on each router, add an IP interface to the VLAN, assign a port to the 
VLAN, and assign a router identification number to the routers. For the backbone, the network design in 
this case uses slot 2, port 1 as the egress port and slot 2, port 2 as ingress port on each router. Router 1 
connects to Router 2, Router 2 connects to Router 3, and Router 3 connects to Router 1 using 10/100 
Ethernet cables.

Note. The ports will be statically assigned to the router, 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.

The commands setting up VLANs are shown below:

Router 1 (using ports 2/1 and 2/2 for the backbone, and ports 2/3-5 for end devices):

-> vlan 31

-> ip interface vlan-31 vlan 31 address 31.0.0.1 mask 255.0.0.0

-> vlan 31 port default 2/1

-> vlan 12

-> ip interface vlan-12 vlan 12 address 12.0.0.1 mask 255.0.0.0

-> vlan 12 port default 2/2

-> vlan 10

-> ip interface vlan-10 vlan 10 address 10.0.0.1 mask 255.0.0.0

-> vlan 10 port default 2/3-5

-> ip router router-id 1.1.1.1

These commands created VLANs 31, 12, and 10.

• VLAN 31 handles the backbone connection from Router 1 to Router 3, using the IP router port 

31.0.0.1 and physical port 2/1.

• VLAN 12 handles the backbone connection from Router 1 to Router 2, using the IP router port 

12.0.0.1 and physical port 2/2.

• VLAN 10 handles the device connections to Router 1, using the IP router port 10.0.0.1 and physical 

ports 2/3-5. More ports could be added at a later time if necessary.

The router was assigned the Router ID of 1.1.1.1.
