To start router discovery on the SSR, enter the following command in Configure mode:
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::
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::
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:
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 start
ssr(config)# rdisc add address 10.10.5.254
ssr(config)# rdisc add interface ssr4
ssr#(config) rdisc set address 10.20.36.0 type broadcast preference
ineligible
ssr#(config) rdisc set interface ssr4 max-adv-interval 1200
