Configuring IP Unicast Routing
Configuring OSPF
 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 supported.
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.
