24 Configuring RIP parameters Enabling RIP RIP is disabled by default. To enable RIP, you must enable it globally and also on individual interfaces on which you want to advertise RIP. Globally enabling the protocol does not enable it on individual interfaces. You can enable the protocol on physical interfaces as well as virtual routing interfaces. When you enable RIP on a port, you also must specify the version (version 1 only, version 2 only, or version 1 compatible with version 2). To enable RIP globally, enter the following command. BigIron RX(config)# router rip Syntax: [no] router rip After globally enabling the protocol, you must enable it on individual interfaces. To enable RIP on an interface, enter commands such as the following. 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 BigIron RX 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 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. 666 BigIron RX Series Configuration Guide 53-1001810-01
