RIPng Configuration Guidelines

To configure Routing Information Protocol next generation (RIPng), you include the following statements:

protocols {

    ripng {

        graceful-restart {

            disable;

            restart-time seconds;

        }

        holddown seconds;

        import [ policy-names ];

        metric-in metric;

        receive <none>;

        send <none>;

        traceoptions {

            file name <replace> <size size> <files number> <no-stamp> 

                <(world-readable | no-world-readable)>;

            flag flag <flag-modifier> <disable>; 

        }

        group group-name {

            export [ policy-names ]; 

            metric-out metric;

            preference number;

            neighbor neighbor-name { 

                import [ policy-names ]; 

                metric-in metric;

                receive <none>;

                send <none>;

            }

        }

    }

} 

For a list of hierarchy levels at which you can configure these statements, see the statement summary sections for these statements.

By default, RIPng is disabled.

NOTE: By default, RIPng routes are not redistributed. You must configure export policy needs to redistribute RIPng routes.

To have a router exchange routes with other routers, you must configure RIPng groups and neighbors. RIPng routes received from routers not configured as RIPng neighbors are ignored. Likewise, RIPng routes are advertised only to routers configured as RIPng neighbors.

This chapter discusses the following topics that provide information for configuring and monitoring RIPng:

• Minimum RIPng Configuration
• Defining RIPng Global Properties
• Defining RIPng Neighbor Properties
• Modifying the Incoming Metric
• Configuring the Hold-Down Timer
• Configuring Update Messages
• Applying Import Policy
• Configuring Group-Specific Properties
• Configuring Graceful Restart
• Tracing RIPng Protocol Traffic

For a configuration example, see Example: Configuring RIPng.
