Table 10-2 Default Ospf Configuration - Cisco ONS 15454 Software Feature And Configuration Manual

Configuring IP Routing
Stub areas—Definition of stub areas is supported.
•
Route redistribution—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 and export
routes learned through protocols such as EIGRP and RIP.
Authentication—Plain text and message-digest key (MD5) authentication among neighboring
•
routers within an area are supported.
Routing interface parameter—Configurable parameters supported include interface output cost,
•
retransmission interval, interface transmit delay, router priority, router dead and hello intervals, and
authentication key.
• Virtual links—Virtual links are supported.
Not-so-stubby-area (NSSA)—RFC 1587.
•
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.
