Route Re-Distribution
Both RIP and OSPF can be enabled simultaneously on the device. Route re-distribution allows the
device to exchange routes, including static routes between two routing protocols – RIP and OSPF.
Such a router is called an Autonomous System Border Router (ASBR).
OSPF Timers and Authentication
Configuring OSPF timers and authentication on a per-area basis is shorthand for applying the
timers and authentication to each IP interfaces in the area at the time of configuration. If the user
adds more networks to the area, the user must configure the timers and authentication for the new
IP interfaces explicitly.
OSPF Configuration Flow
Figure 3
displays the process to configure OSPF parameters.
