OSPF Quick Steps Configuring OSPF

OSPF Quick Steps
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 vlan command. For example:
-> vlan 5
-> vlan 5 enable
2 Assign a router IP address and subnet mask to the VLAN using the ip interface 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 6800/6850/9000 Network Configuration Guide.
4 Assign a router ID to the router using the ip router router-id command. For example:
-> ip router router-id 1.1.1.1
5 Load and enable OSPF using the ip load ospf and the ip ospf status 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 ip ospf
area 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
