This attribute represents the learned peer address information. This
address is used to essentially tunnel frames to a peer bridge unit across a
network or a backbone. The tunneled frame is then appropriately
processed by the peer bridge unit. Fddi encapsulated bridging using
FddiETb bridge port and Source route encapsulated bridging using
SrseBridgePort & TbseBridgePort are examples of instances where this
attribute peerAddressInfo is used.
