SUMMARY

The "P" switch for the Route command allows a user to make persistent entries in the routing table by adding a static route directly to the registry.

You can use the "P" switch for the Route command which allows a user to make persistent entries in the routing table by adding a static route directly to the registry. The use of the "P" switch is covered in the online command reference but is not in the printed TCP/IP reference.

Sample syntax from a command line:

route -p add 131.107.3.0 mask 255.255.255.0 131.107.3.1

The command forces the following registry entry to be read when the computer is restarted.

   HKEY_LOCAL_MACHINE
    \SYSTEM
      \CurrentControlSet
        \Services
          \Tcpip
            \Parameters
              \PersistentRoutes

   value: 131.107.3.0 255.255.255.0 131.107.3.1 Reg_SZ:
