, Enterprise A and Enterprise C are on different network segments. To
allow the two enterprises to communicate with each other, IP routing has been configured for
bridge groups. The enterprises, however, cannot communicate with each other. This fault is
commonly caused by one of the following:
l
Physical interfaces fail to be added to bridge groups.
l
Member interfaces in bridge groups become faulty.
l
Routes between the two enterprises are unreachable.
