Creating Persistent Routes (Fixed and Reactive)

The /etc/defaultrouter file is deprecated in Oracle Solaris 11. You can no longer manage routes (default or otherwise) by using this file. Also, after an installation, you cannot determine a system's default route by checking this file. Instead, choose from the following methods to determine the system's default route.

You can configure route information for a system in the following ways:

• For any currently active NCP (fixed or reactive), use the route command with the -p option to persistently add a route:

  # route -p add default ip-address

  Because this command applies the specified route to the currently active NCP, the default route is removed and potentially replaced, if the active NCP changes.

  ---

  Note - This behavior is true for all types of network configuration, not just the default route settings.

  ---

  For routes that are created by using this method, use the route -p show command to display all of the static routes that are associated with the currently active NCP:

  # route -p show

• Display the currently active routes on a system (applies to both types of NCPs) by using the netstat command:

  # netstat -rn

• Create a single, per-interface default route for any reactive NCP (active or non-active) by using the netcfg command. See Example 7-9.

  Display the default route for the NCP, as follows:

  # netcfg "select ncp MY-STATIC; select ncu ip e1000g0; get ipv4-default-route"
          ipv4-default-route      "10.80.226.1" 

  Default routes that are created with the netcfg command can also be viewed by using the netstat -rn command, but only when the relevant NCP is active. Routes that are created in this way cannot be viewed by using the route -p show command.

For more information, see the netstat(1M) and route(1M) man pages.
