OSPF is a scalable, standards-based link-state
routing protocol. OSPF's benefits include no hop-count limitation, the
capability to multicast routing updates, faster convergence rates, and
optimal path selection. The basic steps for OSPF operation are as follows:
- Establish router adjacencies
- Select a designated router and a backup
designated router
- Discover routes
- Select appropriate routes to use
- Maintain routing information
In the next chapter, you will learn how to
connect multiple OSPF areas in order to support a larger hierarchical
routing environment.
