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
• Configure Router Advertisement on an Interface
• Configure the Hop Limit
• Modify the Default Router Lifetime
• Enable Stateful Autoconfiguration
• Configure the Frequency of Router Advertisements
• Modify the Reachable Time Limit
• Modify the Frequency of Neighbor Solicitation Messages
• Configure Prefix Information
• Trace Router Advertisement Traffic
