ICMP Router Discovery Configuration Guidelines

To configure a router as a server for Internet Control Message Protocol (ICMP) router discovery, you can include the following statements in the configuration:

protocols {

    router-discovery { 

        disable;

        traceoptions {

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

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

            flag flag <detail> <disable>;

        }

        interface interface-name {

            min-advertisement-interval seconds ; 

            max-advertisement-interval seconds ; 

            lifetime seconds ; 

        }

        address address {

            (advertise | ignore); 

            (broadcast | multicast); 

            (priority number | ineligible);

        }

    }

} 

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

By default, router discovery is disabled.
