Token Ring Bridge Mode

Figure 2-31. Token Ring Bridge Mode Window

The following options are available in the Token Ring Bridge Mode Window:

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.)

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 

) will be appended to the RIF for frames 

transmitted on the Token Ring.

When the bridge is set to Source Route Transparent, the bridge will transmit both 
transparent and source route frames. The frames received which have source 
route information will be transmitted as source route, while frames received that 
are transparent will be transmitted as transparent.
