The Internet Control Message Protocol (ICMP) Router Discovery protocol
(RFC 1256) allows an appropriately configured end station to locate one
or more routers on the LAN to which it is attached. The end station then
installs a default route to each of the routers that is running ICMP Router
Discovery. You do not need to manually configure a default route. While
IP traffic may initially be directed to any of the routers on the LAN, ICMP
redirect messages subsequently channel IP traffic to the correct router.
Only certain end stations, such as Solaris workstations, can be configured
to work with the ICMP Router Discovery protocol. Refer to the
documentation for your workstation to determine whether you can
configure it to work with this protocol.
To enable ICMP Router Discovery, from the top level of the Administration
Console, enter:
ip icmpRouterDiscovery
Enter the ICMP router discovery mode (
This protocol is disabled by default.
With Extended Switching software you can configure IP Routing
Information Protocol (RIP) on individual interfaces, rather than turning it
on or off for all interfaces.
To display RIP interface configuration information, from the top level of
the Administration Console, enter:
ip rip display
