About routing

[John Wang]

Hello

It's customary to simply put the line:

   GATEWAY=10.10.10.254

Into the /etc/sysconfig/network file.   You'll see that the scripts in
/etc/sysconfig/network-scripts would source the /etc/sysconfig/network file
and then perform the appropriate actions based on the variable GATEWAY.
You'll also notice that the scripts have references to a variable GATEWAYDEV
which indicates you could just specify which network interface to use to get
out instead of the default router specifically.

You'll also notice that twi if the scripts there reference the file
/etc/sysconfig/static-routes if it exists so you can place static routes in
such a file in the following format:

   any net 10.10.11.0/24 gw 10.10.10.254

There's nothing fancy to any of this, it's just script work.

Regards,
John
