Turning On Space-Saving Mode

Space-saving mode provides the host with a table that contains only the default routes. On a host, in.routed runs with space saving mode turned off by default.

If you do not want the host to have a full routing table (which provides increased protection against misconfigured routers), turn space saving mode on. To do so, edit the /etc/rc2.d/S69inet startup script by changing the line:

/usr/sbin/in.routed -q

to

/usr/sbin/in.routed -q -S
