Packets arriving on an RVI that is using Q-in-Q VLANs will get routed regardless of whether
the packet is single or double tagged. The outgoing routed packets contain an S-VLAN
tag only when exiting a trunk interface; the packets exit the interface untagged when
exiting an access interface.
Q-in-Q tunneling does not support most access port security features. There is no
per-VLAN (customer) policing or per-VLAN (outgoing) shaping and limiting with Q-in-Q
tunneling unless you configure these security features using firewall filters.

You can configure Multiple VLAN Registration Protocol (MVRP) on Juniper Networks EX
Series Ethernet Switches. The primary purpose of MVRP is to manage dynamic VLAN
registration in a LAN. In managing dynamic VLAN registration, MVRP also prunes VLAN
information. MVRP can also be used to dynamically create VLANs in switching networks.
MVRP is an application protocol of the Multiple Registration Protocol (MRP) and is
defined in the IEEE 802.1ak standard. MRP and MVRP were designed by IEEE to perform
the same functions as Generic Attribute Registration Protocol (GARP) and GARP VLAN
Registration Protocol (GVRP) while overcoming some GARP and GVRP limitations, in
particular limitations involving bandwidth usage and convergence time in large networks
with large numbers of VLANs.
MVRP was created by IEEE as a replacement application for GVRP. MVRP and GVRP
cannot be run concurrently to share VLAN information in a switching network.

The VLAN registration information sent by MVRP protocol data units (PDUs) includes
the current VLANs membership—that is, which switches are members of which
VLANs—and which switch interfaces are in which VLAN. MVRP shares all information in
the PDU with all switches participating in MVRP in the switching network.
