Proxmox VE (PVE)
The DHCP integration into the built-in PVE IP Address Management stack currently uses dnsmasq for giving out DHCP leases. Does not support EVPN on Proxmox SDN.
To use that feature you need to install the dnsmasq package on every node:
apt update
apt install dnsmasq
# disable default instance
systemctl disable --now dnsmasq
