Add and change a default route in Solaris 10

Add a default route (gateway).

Create an /etc/defaultrouter file with the IP to have it set to this for each boot.

route add default xxx.xxx.xxx.xxx

Change the default route

Step 1: edit /etc/defaultrouter

Using the editor of your choice, edit the file /etc/defaultrouter — the only line in the file should be the default route of the system, for example: 192.168.1.1. This change will not take effect until the system is rebooted.

Step 2: Delete the current default route

To make the route change take effect immediately, you must first delete the default route. If the current default route is 192.168.254.1, then the command would be:

route delete default 192.168.254.1

Step 3: Assign the current default route

To implement the new default route without rebooting the system, use the following command substituting your default route for 192.168.1.1:

route add default 192.168.1.1
