This feature extends the multi-domain EVPN VXLAN feature introduced to support interconnect with EVPN MPLS networks. The following diagram shows a multi-domain deployment with EVPN VXLAN in the data center and EVPN MPLS in the WAN. Note that this is the only supported deployment model, and that an EVPN MPLS network cannot peer with an EVPN MPLS network.

This feature adds all-active (A-A) multihoming support on the multi-domain EVPN VXLAN-MPLS gateway. It allows L2 and L3 ECMP to form between the multihoming gateways on the TOR devices inside the site and on the gateways in the remote sites. Therefore, traffic can be load-balanced to the multi-homing gateway and redundancy and fast convergence can be achieved.

PIM External Gateways (PEGs) allow an EVPN overlay multicast network to interface with an external PIM domain. They can be used to interconnect two data centers using an external PIM domain in between them.

Selective ARP install is the selective programming of remote ARPs in hardware as received through EVPN Type 2 MAC-IP routes in an EVPN VXLAN/ MPLS Integrated Routing and Bridging (IRB) scenario. Instead of installing every MAC+IP binding received from EVPN into the hardware, the switch installs them only when there is routed traffic destined to the IP, thereby saving TCAM space on the switch. However, there is a tradeoff as there is an initial one-time latency to install the hardware TCAM entry on the first flow of routed traffic to the IP.

The sFlow VXLAN extension adds support for providing VXLAN-related information to sFlow packet samples, for VXLAN forwarded traffic. Specifically, for customer traffic ingressing on a CE-facing PE interface and forwarded into a VXLAN tunnel, the IP address of the source VTEP, the IP address of the destination VTEP and the VNI will be included in the sFlow datagram.
