Neighbor Discovery Configuration Guidelines

To configure neighbor discovery, you include statements at the [edit protocols router-advertisement] hierarchy level of the configuration. 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>;

            }

        }

    }

} 

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
