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
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
A and Access Switch B. But the Distribution Switch sends traffic for
Switch A.

Understanding Bridging and VLANs on EX Series Switches on page 1501
You can manage network convergence by configuring both a primary link and a secondary
link on a switch; this is called a redundant trunk group (RTG). If the primary link in a
redundant trunk group fails, it passes its known MAC address locations to the secondary
link, which automatically takes over.
