The Model 58000 switch enables you to make each switch its own community
by connecting the switches with forced feeder links.
shows a
configuration where two switches are connected by forced feeder links.

In
, duplicate MAC addressing results from the use of a
bridge/router to carry data between virtual LANs distributed across two switch
communities. Each switch has ports assigned to separate virtual LANs (virtual
LAN A, B, and C). One port from each virtual LAN on each switch is
connected and configured as a feeder port. This configuration allows network
traffic from each virtual LAN to pass between independent switch
communities.
A feeder port from each virtual LAN of switch B is connected to a separate port
on a multiport bridge/router. Network traffic specific to each virtual LAN is
transmitted throughout each virtual LAN between the switch communities,
while the bridge/router directs data between virtual LANs. The feeder link
from each virtual LAN on switch B to the router is seen as a separate segment.
