This Chapter explains the Routing features of the LevelOne WBR-1101TX.
The routing table is accessed by the Routing link on the Options screen.
Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing Table, although is it possible to use both methods simultaneously.
Static Routing Table
If RIP is not used, an entry in the routing table is required for each LAN segment on your Network, other than the segment to which this device is attached.
The other Routers must also be configured. See Router Configuration later in this chapter for further details and an example.
Data - Routing Screen
RIP |
|
Enable RIP
|
Check this to enable the RIP (Routing Information Protocol) feature of the
LevelOne WBR-1101TX.
The LevelOne WBR-1101TX supports RIP 1 only.
|
Static Routing Table |
|
Select Entry
|
This drop-down list shows all entries in the Routing Table.
|
Destination
IP Address |
The network address of the remote LAN segment.
For standard class "C" LANs, the network address is the first 3 fields of this Destination IP Address. The 4th (last) field can be left at 0. |
Network Mask
|
The Network Mask used on the remote LAN segment. For class "C" networks,
the standard Network Mask is 255.255.255.0
|
Gateway
IP Address |
The IP Address of the Router on the LAN segment to which this device is
attached. (NOT the router on the remote LAN segment.)
|
Interface
|
Select the appropriate interface - LAN or WAN from the drop-down
list.
Note: The "WAN" interface it only available if NAT (Network Address
Translation) has been disabled on the Options screen.
|
Metric
|
The number of routers which must be traversed to reach the remote LAN
segment. The default value is 1.
|
Buttons |
|
Clear Form
|
Clears all data, ready for input of a new entry.
|
Add
|
Add a new entry to the Routing table, using the data shown on screen.
The name shown in the drop-down list is ignored.
|
Delete
|
Delete the entry selected in the drop-down list, regardless of whether its
details are shown on screen.
|
Update
|
Update the entry selected in the drop-down list, using the data shown on
screen.
|
List All
|
List all entries in the Routing table.
|
Save
|
Save the RIP setting. This has no effect on the Static Routing Table.
|
Cancel
|
Reverse any changes made since the last "submit" operation (i.e. since
clicking any other button).

It is essential that all IP packets for devices not on the local LAN be passed to the LevelOne WBR-1101TX, so that they can be forwarded to the Internet. To achieve this, the local LAN must be configured to use the LevelOne WBR-1101TX as the Default Route or Default Gateway.
The local router is the Router installed on the same LAN segment as the LevelOne WBR-1101TX. This router requires that the Default Route is the LevelOne WBR-1101TX itself. Typically, routers have a special entry for the Default Route. It should be configured as follows.
Destination IP Address
|
Normally 0.0.0.0, but check your router documentation.
|
Network Mask
|
Normally 0.0.0.0, but check your router documentation.
|
Gateway IP Address
|
The IP Address of the LevelOne WBR-1101TX.
|
Metric
|
1
|
Other routers on the local LAN must use the LevelOne WBR-1101TX's Local Router as the Default Route. The entries will be the same as the LevelOne WBR-1101TX's local router, with the exception of the Gateway IP Address.
For the LAN shown above, with 2 routers and 3 LAN segments, the LevelOne WBR-1101TX requires 2 entries as follows.
