In this topology, two switches are connected back-to-back using two ports on each switch. The spanning tree that is running in the switches is RSTP. Switch 2 is the root bridge in STP.
Interface P1 and P2 in switch 1 and switch 2 must be enabled.
VLAN must be configured.
See Example Topolgy 2 for the topology referenced in this procedure.

The switch propagates the VLAN declaration or registration on all the forwarding ports in the switch. In the preceding example, when VLAN 2 was created on the root bridge (switch 2), the switch propagated this information on all of the forwarding ports (Ex0/3 and Ex0/4), thus allowing switch 1 to learn about VLAN 2 through two ports (Ex0/3 and Ex0/4) using GVRP.
