PIM-DM is independent of the IP routing protocol chosen to
run on your network, hence the name, Protocol Independent Multicast.
This also means that in the same network DVMRP and PIM could
possibly construct divergent source based delivery trees as shown in
Figures 6-1, 6-2, and 6-3. In Figure 6-1, DVMRP is being used as the
multicast routing protocol. Since DVMRP builds routing tables based
on RIP, the source based tree for the network in Figure 6-1 would be
through the 28.8K connections since this path offers a lower hop
count than the path through the T1 connections. |
