[SunHELP] restrict outbound traffic of second interface

[Tim Gallagher]

We have a couple of Solaris 9 boxes and need to configure backups. Each box
has two interfaces, one that is the primary for the running app and a
second, on a different network which we would like to use for the backups.

primary	10.2.2.10
second		10.2.3.15
backup net	10.2.4.0

How do we configure the routing of the second interface (eri2 for example)
to handle only the traffic going out to the backup network? All other
outbound traffic from the box should pass out the primary interface.

>From looking in the archives and google it appears that a simple "route
add"
statement should do it, but the precise syntax eludes me. Also, what is the
best method to have it persist after reboots? ...a start script?

Thanks very much in advance,
