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.
