@mikemallin is this proposal based on the previous community proposals for MH
(#1412) Marvell
(#1622) Broadcom
or is it a fresh new one?
@zhangyanzhao we should converge into one proposal

@Yuval-Mellanox @zhangyanzhao the EVPN MH proposals from Cisco and BRCM are under active review in the Routing WG, the eventual goal is to reach a converged solution for the extended community, I haven't seen a HLD from #1412 yet, but if any org or individual is interested in contributing to EVPN MH, please reachout to the Routing WG sonic-wg-routing@lists.sonicfoundation.dev

This is the proposal that has been presented by Cisco at the Routing WG a few weeks ago.

Hello,

We have a small team of engineer working on the EVPN Multihoming implementation and decided to start from this PR as requirements base.

Can you, please, look at the questions we have regarding the requirements?


```
"ETHERNET_SEGMENT_TABLE:PortChannel01": {
"interface" = "PortChannel01"

Why do we need the same "PortChannel01" in the table name as "interface" field?

### 3.1.3 SAI Overview

Add a new attribute "SAI_BRIDGE_PORT_ATTR_DF_BLOCK" in sai_bridge_port_attr_t to indicate that the bridge port is blocked to forward any BUM traffic received from the Tunnel.

As soon as I understand - we support only VLAN-VNI mapping and not the bridging between vxlan interface and some physical port.
If this is true - we don't need this requirement, right?

Hello! I'd suggest waiting for now as a new, combined HLD is underway.
