l
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.
6.4.1 System Default Gateway Configuration
The system-wide Default Gateway provides three options: Auto (default), User-selected
Network Interface, and None.
l
None:
It allows you to choose to have no Default Gateway in the CPE.
l
Auto (default):
It allows you to enable the Router to automatically decide the Default Gateway.
l
User-selected Network Interface:
It allows you to select a Network Interface from a list (PVCs, PPP
Sessions 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.
?
Note
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.
l
Specify IP:
It allows you to specify the IP address of the default gateway.
6.4.2 Route Configuration
Destination:
It allows you to enter the remote network or host IP address for the static routing.
Netmask:
It allows you to enter the Subnet Mask for the static routing.
Gateway:
It allows you 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:
It displays the static route entries entered by the user.
6.5 Learned MAC Table
Network bridges operate at the physical network layer. The purpose of a bridge is to connect two or more
networks and enable packet sharing between them. Bridges are different from routers because they
forward packets based on physical addresses, whereas routers use IP address to forward packets. Bridges
must learn all the physical (MAC) addresses of the devices so it can forward the packets reliably. The
purpose of the Learned MAC Table is to store and display these bridge-recognized MAC addresses.
The
Learned MAC Table
page shows the current learned Bridge MAC table. This page contains
information that is dynamic and will refresh every 8 seconds.
