Verifying That GVRP Is Updating VLAN Membership on the Distribution Switch
To verify that GVRP is updating VLAN membership on the distribution switch, display
the Ethernet switching interfaces and associated VLANs on the Distribution Switch:
List the Ethernet switching interfaces on the switch:

The Distribution Switch has two trunk interfaces. Interface
Distribution Switch to Access Switch A and is therefore updated to show that it is a
member of all the VLANs that are active on Access Switch A. Any traffic for those VLANs
will be passed on from the Distribution Switch to Access Switch A, through interface
. Interface
xe-0/1/1.0 xe-0/1/0.0
and is updated to show that it is a member of the two VLANs that are active on Access
Switch B. Thus, the Distribution Switch sends traffic for
Switch A and Access Switch B. But the Distribution Switch sends traffic for
Access Switch A.

Simplify the convergence configuration in a typical enterprise network by configuring a
primary link and a secondary link on trunk ports. If the primary link fails, the secondary
link automatically takes over without waiting for normal STP convergence.
This example describes how to create a redundant trunk group:
