Figure 16.1 DVMRP Network
In this example, all routers are running DVMRP.
1.
Host_1 sends an IGMP membership report to Subnet 1.
2.
After Router_C receives this report, it associates its receiving interface,
Ethernet 1/1, with the group reported in the IGMP message, for example,
Group 1.
3.
Source_1 then sends a data packet for Group 1.
4.
Every router creates an(S,G) entry in the multicast routing table.
5.
When the data packet reaches Router_C, it forwards via the interface,
Ethernet 1/1, because there is a local member on this interface for this
group. Router_C has a downstream receiver, hence, it does not send a
prune message to its upstream neighbor router, Router_B.
