System Default Gateway Configuration

Route Configuration
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 connection is already up,
then the route entry appears in the Routing Table immediately. If there is a Gateway
associated with the selected Network Interface, then that Gateway's IP address appears in
the Gateway field of the route entry
If the selected Network Interface is dynamic but the connection is not established, then
the route entry does not appear in the Routing Table. When the interface comes up later,
the route entry is then added.
The system-wide Default Gateway now provides three options: Auto, User-selected
Network Interface, and None.
None: This field allows the user to choose to have no Default Gateway in the CPE
Auto: This field allows the user to select the CPE to automatically decide the Default
Gateway. (System Default)
User-selected Network Interface: This field allows user to select a Network Interface
from a list (PVCs, PPP Sessions, USB and LAN). This option lets the user to associate
the system-wide Default Gateway to a Network Interface, static or dynamic, and provides
a way to fix the Default Gateway to a dynamic Network Interface before the interface is
established.
Destination: This field allows the user to enter the remote network or host IP address for
the static routing.
Netmask: This field allows the user to enter the Subnet Mask for the static routing.
Gateway: This field allows the user to enter the IP address of the gateway device that
allows the router to contact the remote network or the host for Specified IP or select an
Interface for the Gateway.
Manually Configured Routes: This field displays the static route entries entered by the
user.
