The Gateway field of the static route entry allows users to either enter a
Gateway IP address or select a Network Interface.
All user-defined routes retained in the CPE memory, regardless if they
are already in the Routing Table, are displayed on the same Route
Table page.
All user defined route entries kept in the CPE memory during run time
are saved to flash when the user chooses to save and reboot the CPE.
When CPE restarts, it reloads all saved user-defined routes to the CPE
memory and tries to apply to the system.
A user-defined route entry is added to the Routing Table whenever the
system provides an environment that makes the route entry applicable.
It is removed from the Routing Table whenever the route entry
becomes not applicable. e.g. If the route entry’s Gateway is associated
with a dynamic Network Interface but the connection is not established,
then the route entry does not appear in the Routing Table. When that
interface comes up later, the route entry is then added.
If the selected Network Interface is static or is dynamic and the
