possible to add ip address on proxmox host in example evpn vnet?

[telvenes]

Hello I tried to add custom config

/etc/network/interfaces
ifcae vxlan
address 10.0.0.21/24

So now all vms can talk to and vms only located on the host that have configured 10.0.0.21/24 can ping 10.0.0.21, but if i move the vm to another host 10.0.0.21 no longer responds.
Is this even possible or how can this be done?
