I stumbled upon this archived [post](https://www.reddit.com/r/Arista/comments/azubnz/mlag_or_esi/) while researching EVPN support specifically on the EVPN multihoming side using common ESIs to extend beyond 2 switches in a LAG.

Also this is the only post I’ve found mentioning EVPN Multihoming – https://eos.arista.com/arista-layer-2-vtep-evpn-vxlan-route-type-1-support/ but is limited to using mlag only.

Does anyone have any information on when there will be support for the EVPN ESI LAGs?

Since 4.22.0F there is support for ESI

https://eos.arista.com/eos-4-22-0f/evpn-vxlan-all-active-multihoming/

Multi-homing is activated in an EVPN environment by assigning an ethernet segment identifier to the participating Ethernet or Port-Channel interfaces.


interface Ethernet1
evpn ethernet-segment
identifier 00aa:bbbb:cccc:dddd:eeee
route-target import 12:23:34:45:56:67
