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.
The additional routing metric here is to add input or output metric for routes
obtained for RIP. The
RIP receiving routes on the interface, then add this route metric value in the routing
table. The
rip metricout
routing table, but will add a designated metric value when sending routes on the
interface.
Perform the following configurations in interface view.
Table 481 Specify Additional Route Metric Value for RIP
Operation
Specify additional route metric value
received for RIP
Restore the additional route metric value
received for RIP to its default value
Specify additional route metric value being
advertised for RIP
Restore the additional route metric value
being advertised for RIP to its default value
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.
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.
