•
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 the 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 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.
System Default Gateway Configuration
The system-wide Default Gateway provides three options: Auto (default), User-selected
Network Interface, and None.
None:
This field allows you to choose to have no Default Gateway in the CPE
Auto:
This field allows you to enable the Bridge/Router to automatically decide the
Default Gateway.
User-selected Network Interface:
This field allows you to select a Network Interface
from a list (PVCs, PPP Sessions, USB and LAN). This option allows you 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.
The options for this field are IP PVC0 ... IP PVC7, IP Ethernet 0, IP BridgeMux0,
and any PPP session that was created by the user.
Specify IP:
This field allows you to specify the IP address of the default gateway.
