Bridging

Bridge Methods
The options available in the Bridge Method Þeld are as follows:
Transparent
When the bridge is set to Transparent mode, the bridge will only transmit
transparent frames from the Token Ring connection. If a source route frame is
received by the bridge, the Source Route information in the frame will be dropped
from the packet. (A transparent frame is the same as a source route frame without
a RIFÑRouting Information Field.)
Source Routing
When the bridge is set to Source Routing mode, the bridge will only transmit
source route frames from the Token Ring connection.You should set the bridging
mode to Source Route when you are bridging from Ethernet to Token Ring. The
source route information (as conÞgured via the Ethernet portÕs Source Route
ConÞguration window, page 2-57) will be appended to the RIF for frames
transmitted on the Token Ring.
