Change the default route in Solaris

Posted July 11, 2003 by Quinn McHenry in Solaris networking

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: 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, then the command would be:

route delete default

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

route add default

  • Adrien HEBRARD

    Faster on Solaris 10:

    route change default

    This should be run for permanent modification:

    route -p change default

    If you want to make the route persistent, use this:

      Make sure your setting is in /etc/defaultrouter and /etc/hosts as the “router” entry
