Figure 192: HSR multicast topology
Only about half of the network bandwidth is available in HSR for multicast or broadcast frames because both
duplicate frames A & B circulate the full ring.
5.3.2 HSR UNICAST TOPOLOGY
With unicast frames, there is just one destination and the frames are sent to that destination alone. All non-
r
ecipient devices simply pass the frames on. They do not pr
ocess them in any way. In other words, D frames are
produced only for the receiving DANH. This is illustrated below.
