Configuring RIP parameters
24
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-e1000-1/1)# ip rip v1-only
Syntax: [no] ip rip v1-only | v1-compatible-v2 | v2-only
Configuring metric parameters
By default, a device port increases the cost of a RIP route that is learned or advertised on the port
by one. You can configure individual ports to add more than one to a learned or advertised route’s
cost.
Changing the cost of routes learned or advertised on a port
By default, a device port increases the cost of a RIP route that is learned on the port. The device
increases the cost by adding one to the route’s metric before storing the route.
You can change the amount that an individual port adds to the metric of RIP routes learned on the
port.
To increase the metric for learned routes, enter commands such as the following.
BigIron RX(config-if-e1000-1/1)# ip rip metric-offset 5 in
The command configures port 1/1 to add 5 to the cost of each route it learns.
Syntax: [no] ip rip metric-offset <num> in | out
The number is 1-16. A route with a metric of 16 is unreachable. Use 16 only if you do not want the
route to be used. In fact, you can prevent the device from using a specific port for routes learned
though that port by setting its metric to 16.
In applies to routes the port learns from RIP neighbors.
Out applies to routes the port advertises to its RIP neighbors.
Changing the administrative distance
By default, the device assigns the default RIP administrative distance (120) to RIP routes. When
comparing routes based on administrative distance, the device selects the route with the lower
distance. You can change the administrative distance for RIP routes.
NOTE
Refer to “Changing administrative distances” on page 767 for a list of the default distances for all
route sources.
To change the administrative distance for RIP routes, enter a command such as the following.
BigIron RX(config-rip-router)# distance 140
The command changes the administrative distance to 140 for all RIP routes.
Syntax: [no] distance <number>
The number is 1 - 255.
