Solaris - How to add a route
To add the route, use the following syntax,
/usr/sbin/route add host [destination ip] [via ip]
Then add this as well to your routes script (so it survives a reboot) in the /etc/rc?.d, i normally just do a find for the routes file in /etc.
find /etc -name *routes*
If there isnt one then you will need to create a route start up script within /etc/rc3.d.
