Monitoring IP Parameters

Configuring Router Discovery
The router discovery server on the SSR periodically sends out router advertisements to
announce the existence of the SSR to other hosts. The router advertisements are multicast
or broadcast to each interface on the SSR on which it is enabled and contain a list of the
addresses on the interface and the preference of each address for use as a default route for
the interface. A host can also send a router solicitation, to which the router discovery
server on the SSR will respond with a unicast router advertisement.
On systems that support IP multicasting, router advertisements are sent to the ‘all-hosts’
multicast address 224.0.0.1 by default. You can specify that broadcast be used, even if IP
multicasting is available. When router advertisements are sent to the all-hosts multicast
