UDE and UDLR Overview

Routing protocols support unidirectional links only if the unidirectional links emulate bidirectional links
because routing protocols expect to send and receive traffic through the same interface.
Unidirectional links are advantageous because when you transmit mostly unacknowledged
unidirectional high-volume traffic (for example, a video broadcast stream) over a high-capacity
full-duplex bidirectional link, you use both the link from the source to the receiver and the equally
high-capacity reverse-direction link, called the "back channel," that carries the few acknowledgements
from the receiver back to the source.
