Solaris 10 routes

If you have a Solaris 10 server with several NIC's and a different subnet plugged into each NIC, you might set up zones to use a specific NIC. In order for the non-global zone to route correctly, you will need to set up routing on the global zone.

I've found that putting in a startup script in /etc/rc3.d/S99add-route doesn't always work.

By the way, I use these commands in the script:

#!/bin/sh
/usr/sbin/ifconfig nxge0 plumb
/usr/sbin/ifconfig nxge1 plumb
/usr/sbin/route add default 10.10.10.1 -ifp nxge0
/usr/sbin/route add default 10.10.20.1 -ifp nxge1

It seems that SUN has added a "-p" flag to the route command that now makes the statement persistent across reboots, rendering the script moot:

# /usr/sbin/route -p add default 10.10.10.1 -ifp nxge0
add net default: gateway 10.10.10.1: entry exists
add persistent net default: gateway 10.10.10.1

# /usr/sbin/route -p add default 10.10.20.1 -ifp nxge1
add net default: gateway 10.10.20.1: entry exists
add persistent net default: gateway 10.10.20.1

The entries are written to the file: /etc/inet/static_routes

# File generated by route(1M) - do not edit.
default 10.10.10.1 -ifp nxge0
default 10.10.20.1 -ifp nxge1
