3.4 RIP Route Control
In actual implementation, it may be needed to control RIP routing information more
accurately to accommodate complex network environments. By performing the
configuration described in the following sections, you can:
z Control route selection by adjusting additional routing metrics on interfaces
running RIP.
z Reduce the size of the routing table by setting route summary and disabling the
receiving of host routes.
z Filter the received routes.
z Set the preference of RIP to change the preference order of routing protocols.
This order makes sense when more than one route to the same destination is
discovered by multiple routing protocols.
z Import external routes in an environment with multiple routing protocols and filter
the advertised routes.
3.4.1 Configuration Prerequisites
Before configuring RIP route control, perform the following tasks:
z Configuring network layer addresses of interfaces so that adjacent nodes are
reachable to each other at the network layer
z Configuring basic RIP functions
3.4.2 Configuring RIP Route Control
I. Setting the additional routing metrics of an interface
Additional routing metric is the routing metric (hop count) added to the original metrics
of RIP routes on an interface. It does not change the metric value of a RIP route in the
routing table, but will be added for incoming or outgoing RIP routes on the interface.
