Note
If you do not want multicast or broadcast traffic from C1 on R1 to be seen by C1
on R3, then configure a different backbone VLAN on R3.
STP/GVRP in Customer VLANs Tunneled over Backbone VLAN
STP, RSTP, or GARP/GVRP can be run in the customer VLANs which are tunneled over the backbone VLAN. The
customer VLAN does not need to be reconfigured in order to be tunneled.
In
, traffic for customer C1’s VLAN (BLUE) and for customer C2’s VLAN (GREEN) is tunneled through
the backbone VLAN (RED). STP is enabled in the customer VLAN BLUE on the customer routers C1R1 and C1R2
for customer C1.
