attached to a network segment. A data packet is not forwarded to another
segment if its destination MAC address resides on the same segment as its source.
To efficiently separate traffic, the bridge maintains a Bridge Forwarding Table. The
table contains a list of MAC addresses and their associated network segments. The
table is built dynamically from the source MAC addresses of data packets passing
through the bridge.
The OfficeConnect Remote 812 bridge supports the Spanning Tree Protocol (STP).
This feature is used when two networks are joined by two bridges forming a
looped network. STP prevents the data packets from circling the two networks.
The OfficeConnect Remote 812 provides a Bridge Firewall function which allows
flexible configuration of simultaneous bridging and routing. For more information
on the Bridge Firewall, see the
Bridging and Routing section.
To set up bridging on the OfficeConnect Remote 812, you must:
■
Configure bridging for the LAN.
■
Configure bridging for the remote site connection .
You may also want to:
■
Set up to bridge IP traffic.
■
Modify advanced bridging options.
Details are provided in the following sections.
Remember to save your configuration using the save all command before
rebooting your OfficeConnect Remote 812 so that your changes will be written to
permanent FLASH memory.
Configuring Bridging for
the LAN
To configure a protocol over the LAN, you need to assign a protocol network to
the LAN port by providing a name. After adding a network, you can modify
advanced parameters.
■
To add a bridge network over the Ethernet interface, use the command:
add bridge network <network name>
You can obtain a list of all configured networks using the command list
networks . To only list bridge networks, use list bridge networks .
■
By default, the network is enabled when it is created. You can disable the
network using the following command:
disable bridge network <network name>
■
You can delete a disabled network using the command:
delete bridge network <network name>
