17 Configuring OSPF
OSPF is an Interior Gateway Protocol (IGP) designed expressly for IP networks, supporting IP
subnetting and tagging of externally derived routing information. OSPF also allows packet
authentication and uses IP multicast when sending and receiving packets.
The implementation conforms to the OSPF Version 2 specifications with these key features:
• Definition of stub areas is supported.
• Routes learned through any IP routing protocol can be redistributed into another IP routing
protocol. At the intradomain level, this means that OSPF can import routes learned through
EIGRP and RIP. OSPF routes can also be exported into RIP.
• Plain text and MD5 authentication among neighboring routers within an area is supported.
• Configurable routing interface parameters include interface output cost, retransmission interval,
interface transmit delay, router priority, router dead and hello intervals, and authentication key.
• Virtual links are supported.
• Not-so-stubby-areas (NSSAs) per RFC 1587 are not supported now.
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 would use all default parameter values, no authentication, and interfaces assigned
to areas. If you customize your environment, you must ensure coordinated configuration of all
routers.
