broadcast routing information indicates all ports that are members of the broadcast distribution

tree: ports that are able to send and receive broadcast frames.

path selection protocol selects the E_Port members of this tree in a manner designed to prevent

broadcast routing loops.

The following fields are displayed:

Member Ports

Member ISL Ports

The broadcast routing information for the ports is displayed as a set of hexadecimal bit maps. Each

bit in a bit map represents a port, with the least significant bit in each row representing port 0, 32,

64, and so on.
