Chapter 7 Configure Switch Features
The OSPF implementation on the switch conforms to the OSPF Version 2
specifications with support for these key features:
• Definition of stub areas.
• Routes that are learned through any IP routing protocol can be
redistributed into another IP routing protocol. At the intradomain level,
OSPF can import routes that are learned through EIGRP and RIP.
OSPF routes can also be exported into RIP.
• Plain text and message digest algorithm 5 (MD5) authentication among
neighboring routers within an area.
• Virtual links.
• Not-so-stubby-areas (NSSAs) per RFC 1587.
To enable OSPF, complete these steps.
1. Create an OSPF routing process.
2. Specify the range of IP addresses to be associated with the routing
process.
3. Assign area IDs to be associated with that range.
OSPF typically requires coordination among many internal routers, area
border routers (ABRs) connected to multiple areas, and autonomous system
boundary routers (ASBRs). The minimum configuration uses all default
parameter values, no authentication, and interfaces assigned to areas. If you
customize your environment, make sure all routers have a coordinated
configuration.
