102 CHAPTER 5: IP ROUTING PROTOCOL OPERATION
Configuring the Default Cost for the Imported Route
When you use the import-route command to import the routes of other
protocols, you can specify their cost. If you do not specify the cost of the imported
route, RIP will set the cost to the default cost, specified by the default cost
parameter.
Perform the following configurations in RIP view.
By default, the cost value for the RIP imported route is 1.
Setting the RIP Preference
Each routing protocol has its own preference by which the routing policy selects
the optimal one from the routes of different protocols. The greater the preference
value, the lower the preference. The preference of RIP can be set manually.
Perform the following configurations in RIP view.
By default, the preference of RIP is 100.
Setting Additional Routing Metrics
The additional routing metric, is the input or output routing metric added to a RIP
route. It does not change the metric value of the route in the routing table, but
adds a specified metric value when the interface receives or sends a route.
Perform the following configuration in VLAN interface view.
By default, the additional routing metric added to the route when RIP sends the
packet is 1. The additional routing metric when RIP receives the packet is 0.
