DHCP with vxlan in pve 8.1.3

[Gerbildral]

Hi,

I'm testing the new SDN feature with some servers that are going in DC soon, I only get DHCP working with the simple zone.
I can recall that I read somewhere that it was only working with the simple zone, is that still true, and if so is there any idea when it will work with vxlan? like a month or like several months?
Or is there way to get it working with the config files?

It will implemented soon for other zone type.
For evpn (layer3 nework), some work need to be done to bind dnsmasq in different vrf.
for vlan/vxlan (layer2 network), We need some kind a /32 anycast ip inside the bridge. (still need some tests).

Nothing too difficult.

Personnally, I'll look at evpn first, as I need it in production. so maybe for next month.

Thanks for your response!
I'll wait a bit then.

Hello Are there any new information on this?
I would like to use DHCP in the vxlans to distribute cross-node DHCP addresses to vms, which are located there together. So far I have an openwrt that does this.

we are still working on it, it should be available for 8.2

It seems that in 8.2 there is still no "DHCP" option in neither EVPN nor VXLAN settings.
Is there any news on this or some scripting way to get the DHCP option to work with them?

it's not yet ready, prelimary patches has been sent to the dev mailing list.

ok, thank you.

For now, I worked around it by installing pfSense in a vm to provide a dhcp server to the evpn and vxlan networks.
I had to switch the network device type in the pfsense vm from virtio to "rtl8139". Afterwards the VMs on any proxmox host receive dhcp leases in both evpn and vxlan.

Hello.

In 8.2.2 it is possible to define subnets and dhcp range) for the VLAN/VNet, but the VM do not get the Ip address from dhcp server. Its is correct for the current state-of-the-art? thank you
