L2PT with Q-in-Q over VXLAN tunnels in EVPN-VXLAN bridged overlay networks

We support Layer 2 protocol tunneling (L2PT) with Q-in-Q for traffic from an access interface to VXLAN tunnel destinations in a bridged overlay (BO) Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) network. You can use this feature with service-provider style or enterprise-style access interface configurations.
We can use L2PT over VXLAN tunnels with all of the Q-in-Q use cases we support for an EVPN-VXLAN network. For Q-in-Q, the device tunnels tagged frames over VXLAN using the VNI of the VLAN in the frame, and tunnels untagged frames using the VNI of the native VLAN.

To enable this feature, configure the l2pt statement at the [edit protocols layer2-control] hierarchy level with the access interface name interface name and the following required options:

• destination vxlan-tunnel: Enable L2PT for traffic toward a VXLAN tunnel destination.
• protocol protocol-name: Specify a protocol to tunnel. Include additional protocol statements for each protocol you want to tunnel.
