Configuring the Pipeline as a Bridge
Enabling bridging

Examples
If IPX Frame=802.3, and Route IPX=Yes and Bridge=No in the Connection
profile, only 802.3 IPX packets are routed; all other packets are dropped.
If IPX Frame=802.3, and Route IPX=Yes and Bridge=Yes in the Connection
profile, 802.3 IPX packets are routed and all other packets are bridged, including
IPX packets in other frame types, AppleTalk packets, NetBios packets, DECnet
and so forth.
If the Pipeline receives an IPX packet in the 802.2 packet frame, it uses the
physical address in that packet to bridge it across all active bridging sessions.
Enabling bridging
The Pipeline has a global bridging parameter that must be enabled for any
bridging connection to work. The Bridging parameter causes the Pipeline unit’s
Ethernet controller to run in promiscuous mode. In promiscuous mode, the
Ethernet driver accepts all packets, regardless of address or packet type, and
passes them up the protocol stack for a higher-layer decision on whether to route,
bridge, or reject the packets.
Note:
Running in promiscuous mode incurs greater processor and memory
overhead than the standard mode of operation for the Ethernet controller. On
heavily loaded networks, this increased overhead can result in slower
performance, even if no packets are actually bridged.
To enable bridging on Ethernet:
1
Open the Ethernet > Mod Config > Ether Options.
2
Turn on the global bridging parameter.
Bridging=Yes
3
Close the Ethernet profile.
