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 filename <files number> <size size> <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 include these statements, see the statement summary sections for these statements.

By default, router discovery is disabled.
