Bridging - 3Com OfficeConnect Remote 812 Cli User's Manual

Bridging

set ipx network <network name>
sap [BOTH | DISABLE | LISTEN | RESPOND_ONLY | SEND]
Other permutations of the set ipx network command can be used to configure
advanced RIP features and policies.
IPX RIP and SAP can be enabled or disabled for each remote site connection. You
cannot individually enable or disable RIP or SAP; they are enabled or disabled
together for each remote site connection. You can configure whether the
OfficeConnect Remote 812 should advertise local routes and services, only listen
for routes and services from the remote site, or both.
To configure IPX RIP and SAP for the remote site connection, use the


command:
set vc < vc name>
ipx_routing [ALL | LISTEN | NONE | RESPOND | SEND]
A bridge connects two or more physical networks together to function as one big
network. The OfficeConnect Remote 812 can be configured to be a learning
bridge. A learning bridge does more than just link networks; it separates network
traffic and forwards only the packets that need to be forwarded.
Bridges separate traffic by examining the Media Access Control (MAC) addresses
contained in data packets. MAC addresses uniquely identify each machine
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:
