network to the next along the communications path.
bridging, the device learns MAC addresses by remembering source MAC addresses in
frames. Any incoming packet containing a destination address that is not found in the
MAC table is forwarded.
bridging, all forwarding decisions are based on the route information field.
Because Ethernet devices generally do not support source routing, and Token Ring
devices generally do not support transparent bridging, translational bridging provides the
connectivity link for Token Ring and Ethernet networks.
bridging to enable communication in mixed Ethernet/Token Ring environments.
bridging and bridging between both networks.
across multiple links. Like a bridge, a router makes forwarding decisions based on information
stored in its table. However, a router does not have the anonymity of a bridge. It is known to the
workstations using its services, and a protocol must be loaded to connect it to those
workstations.
