One IP interface is required for each desired network (range of IP addresses)
being assigned to an OSPF area on the switch.
2. (Optional) Configure the router ID.
The router ID is required only when configuring virtual links on the switch.
3. Enable OSPF on the switch.
4. Define the OSPF areas.
5. Configure OSPF interface parameters.
IP interfaces are used for attaching networks to the various areas.
6. (Optional) Configure route summarization between OSPF areas.
7. (Optional) Configure virtual links.
