Neighbor Discovery Configuration Guidelines

To configure neighbor discovery, you include the following statements. You configure router advertisement on a per-interface basis.

protocols {

    router-advertisement { 

        interface interface-name {

            current-hop-limit number;

            default-lifetime seconds;

            (managed-configuration | no-managed-configuration);

            max-advertisement-interval seconds;

            min-advertisement-interval seconds;

            (other-stateful-configuration | no-other-stateful-configuration);

            prefix prefix {

                (autonomous | no-autonomous);

                (on-link | no-on-link);

                preferred-lifetime seconds;

                valid-lifetime seconds;

            }

            reachable-time milliseconds;

            retransmit-timer milliseconds;

            traceoptions {

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

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

                flag flag <detail> <disable>;

            }

        }

    }

} 

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

This chapter describes the following tasks for configuring and monitoring neighbor discovery router advertisement messages:

• Minimum Neighbor Discovery Configuration
• Configuring Router Advertisement on an Interface
• Configuring the Hop Limit
• Modifying the Default Router Lifetime
• Enabling Stateful Autoconfiguration
• Configuring the Frequency of Router Advertisements
• Modifying the Reachable Time Limit
• Modifying the Frequency of Neighbor Solicitation Messages
• Configuring Prefix Information
• Tracing Router Advertisement Traffic
