Chapter 8: IP Routing Configuration Guide
The following example displays the contents of the routing table. It shows that some of the
route entries are for locally connected interfaces (“directly connected”), while some of the
other routes are learned from RIP.
To display additional IP information, enter the following command in Enable mode:
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
address or an interface is configured for the limited broadcast address 255.255.255.255, the
router advertisement includes all IP addresses configured on the physical interface. When
router advertisements are sent to a net or subnet broadcast, then only the address
associated with the net or subnet is included.
