Figure 2-13. Multiple edge switches across switch communities
In this configuration, ports 1 and 2 of switch C, port 1 of switch D, and port 2 of
switch F are all configured for feeder mode and are all part of the same virtual
LAN. All feeder ports are designated active feeder ports—standby feeder links
can be detected only on the local switch. No data loop occurs because the
master switch in community 2 (switch D) has a higher priority than the edge
switch in the switch C community.
