Bidirectional Shared Tree Distribution

Bidirectional Shared Tree Distribution
Bidirectional shared tree distribution operates somewhat differently. If a receiver lives upstream
from the RP, it can receive data directly from the upstream source. Figure 19.14 depicts how this
works. As you can see, Host A is a source for group 224.2.127.254, and Host B is a receiver of
that same group. In a bidirectional shared tree, data goes directly from Host A to Host B without
having to come from the RP.
