Chapter 42 Configuring IP Unicast Routing
Configuring OSPF
• 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 1587are supported.
OSPF typically requires coordination among m
any 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.
