58.3 RIP Configuration Task
58.3.1 Starting the RIP
To activate the RIP, the following steps shall be carried out under the global configuration mode:
Command Purpose
router rip
Activate the RIP Routing Process and enter the router
configuration mode.
network
network-number <network-mask>
Appoint the Network Number relevant to the RIP
Routing Process
58.3.2 Allowing the mono-broadcasting updtaed and grouped by RIP
Router
The RIP is a broadcasting-Type Protocol. If you would like the updating of routes to to access to the non-
broadcasting type network, the router shall be configured so as to enable information exchange. To this
end , the following commands shall be used under router configuration mode:
Command Purpose
neighbor
ip-address Define a neighbor router to exchange with it the
Routing Information.
In addition, if you would like to control which interface(s) that can be used to exchange routing information, the
command "ip rip passive" can be used to designate an interface or some interfaces prohibiting the sending of
the update of routes. If necessary, please refer to the relevant discussion on the route filtration in the "Filtrating
the Routing Information" in the Chapter of " Protocol-Independent Commands in Configuring IP Router”.
58.3.3 Using the Offsets on the Route metric
Offset List is taken to increase an offset on the Input and Output Routes, which have been learned with the
RIP. On the other hand, you can use the Access List or the interface to limit the Offset List. In order to increase
the Route metric, the following commands should be executed in the router configuration mode:
Command Purpose
offset-list
[
interface-type
number]|*
{
in
|
out
} access-list-name
offset
Increase an offset on the route metric.
58.3.4 Regulating the Timer
Routing protocols use several timers to determine the frequency for sending the updating of routes, how long
the router will become invalid and other parameters. You can regulate these timers so as to make the
performance of the Routing Protocols more suitable to the requirements of the network.
It is also possible to regulate the Route Protocol to accelerate the Convergence Time of all kinds of the IP
Routing computation, to quickly backup to the redundant router so as to minimize the time of quick recovery.
To regulate the Timer, the following commands should be used under router configuration model.
