  1. Using the Proxmox SDN to manage host connectivity with BGP

    Hello, We're currently trying out using the Proxmox SDN to manage not only guests (using the EVPN controller), but also host connectivity using BGP to experiment with interface redundancy using L3 protocols. It's a bit spotty of course since it obviously wasn't planned for that, but I wanted to...
  2. EVPN SDN not working across multiple nodes

    I'm trying to setup an EVPN based SDN across 2 proxmox nodes. I have 2 nodes with EVPN setup (and they have peered and are exchanging prefixes). These nodes also peer over standard BGP using the BGP controller to my switch, which is receiving the subnets. My switch is configured for ECMP, and I...
  3. VXLan Error 512 disable_ipv6

    Dear Proxmox-Team and other users, I am currently working on a proxmox-lab combining a root server and a lab server at home. I've establshed an VXNat-Zone at the cluster level and a Vnet based on this. After some testing I changed the network-setup of my Cloud-Init Guest and since this point...

  5. SDN VXLAN for private network in a cluster - how to configure properly?

    Hi Proxmoxers out there ;) here is an abstraction of what I finally want to achieve in general: That means: There is a cluster of at least two PVEs behind a firewall managed by PVE An actor should be able to access the PVEs via SSH Within the cluster I want to have an internal network In...
  6. BGP-EVPN SDN and DNAT across multiple hypervisor hosts

    Greetings, I have set up a test environment for BGP EVPN SDN as follows: * 3 hypervisor hosts running pve-manager/7.2-7/d0dd0e85. * Each hypervisor has a public IP and is set up as an exit node with SNAT. * Each hypervisor has a private IP that is used to create the BGP EVPN peering. The...

    Hi, I'm working on setting up SDN in a new cluster. The first question is about the physical network topology. Option 1) --------- -- ISP -- --------- | V ----------------------- -- OpnSense Firewall -- ----------------------- | V ---------------------------- -- Proxmox...
  8. Proxmox 7.2 SDN Creation Issue

    Good day, I'm having an issue creating a VLAN based SDN. The Zone creates without a problem. It is associated with a bridge that has no IP address so that the zone is fully segregated. However, when I configure and submit Vnets within the zone all of the vnets show as being in error. The...
  9. [SOLVED] SDN nodes out of sync.

  10. SDN: To be VLAN aware or not? Or another problem?

    I'm experimenting with the SDN service and have not been able to figure this one out: If I create a Vnet (in my case 11) and tick "VLAN aware", then I cannot define a subnet. If, on the other hand, I untick "VLAN aware", I can define a subnet. What is the point of this and how does one...
  11. [SOLVED] SDN with EVPN Controller

    Hello, I have been exploring SDN and wanted to try it on Proxmox. Right now, I have an experimental cluster with two nodes. The first thing I noticed is that there aren't the well-known SDN controllers like OpenDaylight, Ryu, and the others. And I'm not familiar with EVPN or BGP as...
  12. [SOLVED] SDN: VXLAN with BGP EVPN. Cannot add VLAN tag to guest interface

    Hi, I am testing VXLAN with BGP EVPN with Proxmox 7.1 SDN. BGP and EVPN seem to be working fine, and I can route traffic on VM interfaces that do not specify a VLAN tag. However, when I try to set a VLAN tag on a guest VM NIC which is using a VXLAN VNET, I get the following error: no physical...
  13. VXLAN SDN Network with MTU <1280 means Containers and VMs cannot start

    I have deployed a VXLAN setup on my homelab cluster and I can get connectivity between containers on various hosts, as long as the MTU on the VXLAN zone is greater than or equal to 1280 (the minimum size of MTU in IPv6). My intended final state is one where the VXLAN networking is encapsulated...
  14. [SOLVED] Move pveproxy/web gui to VLAN interface

    Hello, After putting some thought into it I would like to move my proxmox GUI to another interface. Here is what I want to accomplish: Take the gui off of this address 192.168.10.3 auto vmbr0 iface vmbr0 inet static address...
  15. [SDN] Wrong automatic VXLAN configuration to use it over wiregaurd

    Hi everyone, i test the last days SDN on my cluster (v7.1-10, lasted updates) and detect some problem with VXLAN over wireguard. The automatic create config is something like this for three nodes: auto <zone_name>_<vnet_name> iface <zone_name>_<vnet_name> vxlan-id <vnet_id>...
  16. SDN Networking Issue - Missing Vnets

    Hello all, I am very new to the PVE world, and I am trying to test the SDN beta feature. During initial configuration I am running into an issue that is not posted anywhere. I have installed the libpve-network-perl & ifupdown2 packages, everything seems to go smoothly when creating controllers...
  17. SDN + netns: namespaces, bridging and VLANS

    Mainly, it would be fantastic if someone could give me a "here be dragons" on using Proxmox SDN with policy-based routing (i.e. multiple gateways with iproute2 tables + `ip rule`). I would like some more advanced networking (e.g. multiple NICs: i have will have 4 very soon). In configuring...

    We have been working for long time on the deployment of a cluster based PVE and the new SDN feature. We have had the chance to work with BGP expert and also some of the people involved in the dev. of the project. So this report is a bug report after we moved the cluster to v.7 of Proxmox. We...
  20. SDN group/pool permissions

    I'm trying out the experimental SDN feature and am confused on how to assign permissions to use a zone or vlan vnet to a group, or how to add it as a resource to a pool. The documentation states "It’s also possible to add permissions on a zone, to restrict user to use only a specific zone and...
