It does require some features to be turned on concurrently. The basis of this functionality is setting up a single VNI per VPWS service, and binding the VNI to a VLAN on two endpoints like you would do for a "normal" EVPN L2VPN. The only difference would be that you would not enable generation of Type-2 routes (redistribute learned) for the VNI that houses this service.</div><div><br></div><div>As per version 4.22.0F Arista also supports Layer 2 Control Plane Forwarding on a selection of platforms (7020, 7280 and 7500 series).

<br>
Arista documentation is sometimes hard to navigate... but one of<br>
you might know.<br>
<br>
A few days ago, on one of the neighbouring lists, the subject of<br>
EVPN pseudowires was brought up (EVPN-VPWS, RFC 8214), as in <br>
"transparent point-to-point pseudowire, without MAC lookups, possibly<br>
even forwarding all sorts of control packets (STP BPDUs, LLDP, ...)".<br>
<br>
So - can Arista do that? If yes, which software versions and on <br>
which platforms?<br>
