Network requirements
As shown in Figure
link. Enable bridging on the FR sub-interfaces Serial2/0.1 and Serial2/0.2 so that
traffic between Host A and Host B can be bridged through bridge set 1 and traffic
between Host C and Host D can be bridged through bridge set 2.
In this example, Router B is a DCE device.
119, Router A and Router B are interconnected through a FR
