Operation Manual

5.7.4 Route Table

The Route Table page displays routing table and allows the user to manually enter the

routing entry. The routing table will display the routing status of Destination, Netmask,

Gateway, and Interface. The interface br0 means the USB interface; lo0 means the

loopback interface; and ppp1 means the PPP interface. The Gateway is the learned

Gateway

New Enhancement for Routing Table

• 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.
