Hierarchy Level


Use this statement to enable seamless interconnection of:

  • EVPN-VXLAN points of delivery (PODs) in a data center.

  • Different EVPN-VXLAN data centers. This use case is also known as data center interconnect (DCI).

In these use cases, a Juniper Networks device that supports the seamless EVPN-VXLAN stitching feature can serve as either a spine or super spine device that interconnects the PODs or data centers through an EVPN-VXLAN WAN network.

When configuring the interconnection, you can set up a single routing instance of type virtual-switch or evpn on each spine or super spine device. Or, you can use the default switching instance. In the instance, you specify these elements:

  • Two sets of route distinguishers and route targets. The first set is for the POD or data center network. The second set, which you specify in the interconnect configuration stanza, is for the WAN network.

  • An Ethernet segment identifier (ESI) if a spine or super spine device is multihomed in all-active mode using an aggregated Ethernet interface.

  • Peer gateway configurations for Active-Active redundancy with the interconnect-multihoming-peer-gateways statement set under global prorocols evpn.


    When configuring the ESI, keep in mind that the seamless EVPN-VXLAN stitching feature does not support single-active mode, the auto-derive lacp option, or the source-bmac option.

  • All or a list of VXLAN network identifiers (VNIs) that the spine or super spine device translates when different VNIs are configured for the same VLAN in the PODs or data centers, and WAN. For more information about setting up VNI translation, see translation-vni and interconnected-vni-list.

After you configure these elements, the EVPN control plane stitches the EVPN routes from the POD or data center network and from the WAN network into a single MAC forwarding table.


The remaining statements are explained separately. Search for a statement in CLI Explorer or click a linked statement in the Syntax section for details.
