This feature extends the BGP Layer 3 VPN Import/Export and VRF Route Leaking functionality to “default” VRF.

To use IPv6 addresses for VXLAN underlay, there are two different approaches.  The first approach is to make use of

This feature enables support for Macro Segmentation Service (MSS) to insert security devices into the traffic path

Multihoming in EVPN allows a single customer edge (CE) to connect to multiple provider edges (PE or tunnel endpoint). In any multihoming EVPN instance (EVI), for each ethernet segment a designated forwarder is elected using EVPN type 4 Ethernet Segment (ES) routes sent through BGP. In single-active mode, the designated forwarder (DF) is responsible for sending and receiving all traffic. In all-active mode, the DF is only used to determine whether broadcast, unknown

E-Tree is an L2 EVPN service (defined in RFC8317) in which each attachment circuit (AC) is assigned a role of Root or Leaf.

EVPN MPLS VPWS (RFC 8214) provides the ability to forward customer traffic to / from a given attachment circuit (AC)

EVPN Multihoming defines a mechanism for Multihoming PEs to quickly signal, to remote PEs, a failure in an Ethernet Segment (ES) connectivity with the use of Ethernet A-D per ES route

Multihoming in EVPN allows a single customer edge (CE) to connect to multiple provider edges (PE or tunnel endpoint).

In EVPN, an overlay index is a field in type-5 IP Prefix routes that indicates that they should resolve indirectly rather than using resolution information contained in the type-5 route itself. Depending on the type of overlay index, this resolution information may come from type-1 auto discovery or type-2 MAC+IP routes. For this feature the gateway IP address field of the type-5 NLRI is used as the overlay index, which matches the target IPv4 / IPv6 address in the type-2 NLRI.

As described in the L3 EVPN VXLAN Configuration Guide, it is common practice to use Layer 3 EVPN to provide multi

Flexible cross-connect service is an extension of EVPN MPLS Virtual Private Wire Service (VPWS) (RFC 8214). It allows for multiplexing multiple attachment circuits across different Ethernet Segments and physical interfaces into a single EVPN VPWS service tunnel while still providing single-active and all-active multi-homing.

In EOS 4.22.0F, EVPN VXLAN all active multi homing L2 support is available. A customer edge (CE) device can connect to

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

This solution allows delivery of IPv6 multicast traffic in an IP-VRF using an IPv4 multicast in the underlay network. The protocol used to build multicast trees in the underlay network is PIM Sparse Mode.

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.

As of EOS 4.22.0F, EVPN all active multihoming is supported as a standardized redundancy solution. For effective

This solution allows the delivery of customer BUM (Broadcast, Unknown unicast and Multicast) traffic in a VLAN using

This solution optimizes the delivery of multicast to a VLAN over an Ethernet VPN (EVPN) network. Without this solution IPv6 multicast traffic in a VLAN is flooded to all Provider Edge(PE) devices which contain the VLAN.

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.
