For reasons that involve router reliability, you might not want your hosts to use RDISC. If the automatic selection of RIP rather than RDISC by a host is to work reliably, the routers in the network (particularly those that run RDISC) must also work reliably.
If your routers are not running RDISC and you install a single Solaris router, by default all hosts that are connected to that router rely on that router alone. To have the hosts on that network use the other routers as well, turn off RDISC on the new router.
