Using the BayStack 410-24T 10BASE-T Switch
One client, connected to S2, responds with a host membership report. Switch S2
intercepts the report from that port, and generates a proxy report to its upstream
neighbor, S1. Also, two clients connected to S4 respond with host membership
reports, causing S4 to intercept the reports and to generate a consolidated proxy
report to its upstream neighbor, S1.

Switch S1 treats the consolidated proxy reports from S2 and S4 as if they were
reports from any client connected to its ports, and generates a consolidated proxy
report to the designated router. In this way, the router receives a single
consolidated report from that entire subnet.
