Use route redistribution to exchange route information between routing protocols. You
can redistribute the following types of routes into the RIP routing instance in the same
VR:
Routes learned from BGP
Routes learned from OSPF
Directly connected routes
Imported routes
Statically configured routes
When you configure route redistribution, you must first specify a route map to filter the
routes that are redistributed.
In large internetworks where hundreds or even thousands of network addresses can exist,
routers can become overly congested with route information. After you have redistributed
a series of routes from an external protocol to the current RIP routing instance, you can
bundle the routes into one generalized or summarized network route. By summarizing
multiple addresses, you enable a series of routes to be recognized as one route, simplifying
the process.
Using route summarization in a large, complex network can isolate topology changes
from other routers. An intermittently failing link in a domain does not affect the summary
route, so no router external to the domain needs to modify its routing table due to the
link failure.
You can summarize inter area routes or external routes.

By default, RIP is disabled on all interfaces in the VR. You must enable RIP on an interface
before RIP can use that interface to transmit receive packets. When you disable RIP on
an interface, RIP does not transmit or receive packets on the specified interface, but
interface configuration parameters are preserved.
For instructions for configuring RIP settings on the virtual router and on the interface, see
the Network and Security Manager Online Help.
