420 CHAPTER 28: CONFIGURING RIP
Since the route metric of route import cannot be reverted, the dynamic route
information may be significantly distorted. Therefore, route import is done
cautiously to prevent loss of RIP protocol's performance.
Specifying Additional
Route Metric Values for
RIP
The additional routing metric here is to add input or output metric for routes
obtained for RIP. The rip metricin will add a designated metric value while
receiving routes on the interface, then add this route metric value in the routing
table. The rip metricout does not directly change the route metric value in the
routing table, but will add a designated metric value when sending routes on the
interface.
Perform the following configurations in interface view.
Tabl e 481 Specify Additional Route Metric Value for RIP
By default, the additional route metric value received for RIP is 0 but ranges from 0
to 16. Additional route metric value being advertised for RIP is 1, ranging from 1
to 16.
Setting Route Preference Each routing protocol has its own preference that decides which routing protocol
is used to select the best route by IP route strategy. The greater the value is, the
lower the preference. RIP preference can be set manually.
Perform the following configurations in RIP view.
Tabl e 482 Set Route Preference
By default, the RIP route preference is 100.
Configuring Route
Distribution for RIP Perform the following configurations in RIP view.
Configure filtering route information received by RIP.
