Configuring VXLAN EVPN Multihoming
Upon receiving the ARP request, the local cache is checked to see if the response can be locally generated.
If the cache lookup fails, the ARP request can be flooded. This helps with the detection of the silent hosts.

See the following limitations for ESI ARP suppression:
• ESI multihoming solution is supported only on Cisco Nexus 9300 Series switches at the leafs.
• ESI ARP suppression is only supported in L3 [SVI] mode.
