Ethernet VPN (EVPN) networks normally require some measure of redundancy to reduce or eliminate the impact of outages and maintenance. RFC7432 describes four types of route to be exchanged through EVPN, with a built-in multihoming mechanism for redundancy. Prior to EOS 4.22.0F, MLAG was available as a redundancy option for EVPN with VXLAN, but not multihoming. EVPN multihoming is a multi-vendor standards-based redundancy solution that does not require a dedicated peer link and allows for more flexible configurations than MLAG, supporting peering on a per interface level rather than a per device level. It also supports a mass withdrawal mechanism to minimize traffic loss when a link goes down.

This feature enables support for an EVPN VxLAN control plane in conjunction with Arista’s OpenStack ML2 plugin for

Starting with EOS release 4.22.0F, the EVPN VXLAN L3 Gateway using EVPN IRB supports routing traffic from one IPV6

Typical Wi Fi networks utilize a single, central Wireless LAN Controller (WLC) to act as a gateway between the

In VXLAN networks, broadcast DHCP requests are head-end-replicated to all VXLAN tunnel endpoints (VTEP). If a DHCP relay helper address is configured on more than one VTEP, each such VTEP relays the DHCP request to the configured DHCP server. This could potentially overwhelm the DHCP server as it would receive multiple copies of broadcast packets originated from a host connected to one of the VTEPs.

4.22.1F introduces support for ip address virtual for PIM and IGMP in MLAG and Vxlan. On a VLAN, the same IP address can

Several customers have expressed interest in using IPv6 addresses for VXLAN underlay in their Data Centers (DC). Prior to 4.24.1F, EOS only supported IPv4 addresses for VXLAN underlay, i.e., VTEPs were reachable via IPv4 addresses only.

This feature provides the ability to interconnect EVPN VXLAN domains. Domains may or may not be within the same data

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.

[L2 EVPN] and  [Multicast EVPN IRB] solutions allow for the delivery of customer BUM (Broadcast, Unknown unicast

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.

By default, when an SVI is configured on a VXLAN VLAN, then broadcast, unknown unicast, and unknown multicast (BUM) traffic received from the tunnel are punted to CPU. However, sending unknown unicast and unknown multicast traffic to CPU is unnecessary and could have negative side effects. Specifically, these packets take the L2Broadcast CoPP queue to the CPU. 

Overlay IPv6 routing over VXLAN Tunnel is simply routing IPv6 packets in and out of VXLAN Tunnels, similar to

Overlay IPv6 routing over VXLAN tunnel using an anycast gateway (direct routing) has been previously supported using the “ipv6 virtual-router” configuration for both the data-plane and EVPN (or CVX) control-plane learning environments. 

Several customers have expressed interest in using IPv6 addresses for VxLAN underlay in their Data Centers (DC). Prior to 4.27.2F, only IPv4 addresses are supported for VxLAN underlay, i.e VTEPs are reachable via IPv4 addresses only. This feature enables a VTEP to send VxLAN Encapsulated packets using IPv6 underlay.
