VXLAN Layer 3 Gateways Using the Service Provider Style Interface Configuration

In platform-as-a-service (PaaS) and infrastructure-as-a-service (IaaS) deployments, customer cloud and private cloud providers often use the same leaf device to forward their network traffic over a VXLAN core network. Customer cloud and private cloud providers can now use the service provider style interface configuration CLI to configure a leaf device to act as a Layer 3 gateway. They can also use the service provider style CLI to configure multiple interfaces that map to the same VLAN on the same leaf device.

The service provider style CLI is available on the following devices:

• EX4650, QFX5110, QFX5120-32C, QFX5120-48T, QFX5120-48Y, QFX5120-48YM—Starting in Junos OS Release 22.2R1

You can use the service provider style CLI to perform these tasks:

• Configure multiple logical interfaces on a single physical interface.

• Configure your leaf device as a Layer 3 gateway in edge-routed bridging (ERB) and centrally-routed bridging (CRB) overlays.

• Map an integrated routing and bridging (IRB) interface to a virtual network identifier (VNI).

• Perform VXLAN routing.

• Configure an ERB overlay.

• Configure a CRB overlay.

• Configure a VLAN ID.

• Configure a VLAN ID as none.

• Configure a VLAN-aware bundle service.

• Configure a virtual gateway address.

• Map an IRB interface to one VLAN or multiple IRB interfaces to multiple VLANs.

• Assign a VLAN ID to an IRB interface with same VLAN ID as the VLANS IDs or assign a different VLAN ID.
