Defining the Bridge Modes

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 at the Ethernet portÕs Source Route ConÞguration window) will be appended to the RIF for frames transmitted on the Token Ring.

Source Route Transparent

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.

Setting The Token Ring Bridge Mode

1.Click on the radio button next to the bridging mode you would like your Token Ring bridge port to use: Transparent Bridge, Source Routing, or Source Route Transparent.

2.Click on OK to close the window and set the bridge to the desired mode.
