This solution allows delivery of multicast traffic in an IP VRF using multicast in the underlay network. It builds on

Multicast EVPN IRB solution allows for the delivery of customer BUM (Broadcast, Unknown unicast and Multicast) traffic in L3VPNs using multicast in the underlay network. This document contains only partial information that is new or different for the Multicast EVPN Multiple Underlay Groups solution.

[L2 EVPN] and  [Multicast EVPN IRB] solutions allow for the delivery of customer BUM (Broadcast, Unknown unicast and Multicast) traffic in a L2VPN and L3VPNs respectively using multicast in the underlay 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.

Private VLAN is a feature that segregates a regular VLAN broadcast domain while maintaining all ports in the same 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.

Arista MLAG supports STP for Layer 2 loop detection. In fact, most customers enable STP in their MLAG(s) to ensure no

Spanning Tree Protocol requires each interface to have a unique port number ranging from 1 through 4095.  Arista STP typically assigns port numbers to port-channel interfaces in the order in which they are configured.

Prior to 4.25.2F, support for BGP PIC was restricted to locally identifiable failures such as link failures. If a

In EVPN, when configuring the member VLANs for a VLAN aware bundle, the existing configuration command only allows

The feature will provide the ability to error disable local interfaces in a BGP VPWS pseudowire when the remote interface is shutdown or whenever we do not receive a response from BGP.
