Chapter 8: IP Routing Configuration Guide

To start router discovery on the SSR, enter the following command in Configure mode:

ssr(config)# rdisc start

The rdisc start command lets you start router discovery on the SSR. When router discovery is started, the SSR multicasts or broadcasts periodic router advertisements on each configured interface. The router advertisements contain a list of addresses on a given interface and the preference of each address for use as the default route on the interface. By default, router discovery is disabled.

The rdisc add address command lets you define addresses to be included in router advertisements. If you configure this command, only the specified hostname(s) or IP address(es) are included in the router advertisements. For example::

ssr(config)# rdisc add address 10.10.5.254

By default, all addresses on the interface are included in router advertisements sent by the SSR. The rdisc add interface command lets you enable router advertisement on an interface. For example::

ssr(config)# rdisc add interface ssr4

If you want to have only specific addresses included in router advertisements, use the rdisc add address command to specify those addresses.

The rdisc set address command lets you specify the type of router advertisement in which the address is included and the preference of the address for use as a default route. For example, to specify that an address be included only in broadcast router advertisements and that the address is ineligible to be a default route:

ssr#(config) rdisc set address 10.20.36.0 type broadcast preference ineligible

The rdisc set interface command lets you specify the intervals between the sending of router advertisements and the lifetime of addresses sent in a router advertisement. To specify the maximum time between the sending of router advertisements on an interface:

ssr#(config) rdisc set interface ssr4 max-adv-interval 1200
