sdn

Current implementation of EVPN stack explicitly generates blackhole (null0) routes for each VRFs' each subnet that prevents zones to communicate with each other on exit nodes. This behavior is undesired in setups where all nodes are also exit nodes: this happens when the nodes have dedicated...

Hallo zusammen, ich arbeite mich gerade in Proxmox ein und habe zu diesem Zweck einen kleinen 3-node Testcluster als Spielwiese aufgebaut. Nun würde ich gern dafür sorgen, dass für jede VM, die ich erstelle, automatisch ein passender DNS-Eintrag angelegt wird. Dazu würe ich gern die native...

we miss the checkbox to enable vlan-aware in SDN/VNet configuration. Te checkbox is available in GUI vmbr config but not in SDN/vnet configuration. I can set is manually in sdn config file: iface vnet0 hwaddress XX:XX:XX:XX:XX:XX bridge_ports vxlan_vnet0 bridge_stp off...

Hello! As title states, I'm using a Simple SDN zone with auto dhcp enabled, dnsmasq installed, basically everything working. HOWEVER, when I enable the node-level firewall, dhcp stops working entirely. Datacentre firewall doesn't effect dhcp. I have the rules set up from the guide on both a...

Hallo Ladies and Gentlemen, aktuell sammle ich gerade erste Erfahrungen mit Proxmox durch ausprobieren, Kurse etc. . Dabei bin ich auf ein Problem gestoßen, was ich nicht verstehe. Ziel ist es, die VM's und CT's in einem separaten Netzwerk zu betreiben, welches nur Zugang zum GW (Gateway -...

Hi there, is it possible to disable the sdn feature completly? I would like to have my own custom frr configuration not merged with sdn settings. I don't want SDN to change things since what i need is more complex then what can be setup via sdn.

Hi, we have 2 PVE clusters in prod mother cluster with 3 nodes worker cluster with 3 nodes They are more or less identical, have similar SDN configurations etc. Today we made an addition to the SDN configs on both clusters. The mother cluster did fine, but for the worker cluster all vlan...

After successfully using the PBS version of the NIC pinning tool on a couple servers, I tried a PVE 8.4.x server tonight. It seemed fine for most everything except SDN was broken afterwards, showing an error state on the zone (ZoneVLAN). I found file /etc/network/interfaces.d/sdn still...

Hi there, I have a simple sdn zone with 1 VNet and the 1 subnet (10.0.0.0/24, SNAT activated). Several vms are connected to the vnet and they have internet access and can communicate to each other. One vm is connected to the vnet and to my default bridge (vmbr0). It has a public IP (lets say...

I have searched and search, to no avail. Connectivity works from Proxmox 8.x and 9.x hosts to both phpIPAM and PowerDNS. I have tested the connectivity via curl from each host in the cluster. Subnet exists in phpIPAM, zone exists in PowerDNS, and reverse zone exists in PowerDNS. All zones in...

I have a three node Promxox 9 cluster. Each node has a 1GbE NIC and a dual-25GbE NIC (Connect-X 4 Lx). I've been trying unsuccessfully for several days to use Proxmox's SDN capabilities to create a mesh network between the three nodes (by directly connecting the nodes with SFP28 cables) and get...

When a VM is assigned a bridge interface (VLAN aware) with a VLAN tag on the interface and this VLAN also exists as a VNET (same bridge and same VLAN tag) AND is assigned to a VM AND VMs are spread over different hosts, the VM with the bridge assigned directly get all the traffic of the VLAN of...

Hello, I want to set the MTU to 9000 (Jumbo Frames) for my 40Gbit/s OpenFabic, is there any prefferd way to do this with SDN? https://pve.proxmox.com/wiki/Full_Mesh_Network_for_Ceph_Server#Using_SDN_Fabrics I already has set it for the Nics in /etc/network/interfaces but fabric stays at MTU...

I’ve set up two VXLAN SDN zones in Proxmox, each with its own bridge and unique VNI. Example: vxlan_ammmmm: id 2273 dstport 4789 master ammmmm vxlan_i5mnp1: id 528335 dstport 4789 master i5mnp1 Even though the VNIs and bridges are different, VMs in those zones can still ping each other — even...

I need feedback on what I'm experiencing: My Goal Make the FRR merge (SDN-generated /etc/frr/frr.conf + /etc/frr/frr.conf.local) produce the same active configuration I get when I manually apply the changes via vtysh. Currently, that is not the case happening. Environment (facts) Proxmox VE...

I am using the default PVE IPAM plugin with DHCP. I have one zone with a couple of VNets defined, each with separate subnets and certain reserved IPs: For the sake of this post, assume these are all VMs that are configured with DHCP, so they ask for a lease and normally get those static IPs...

Hello, With the major SDN enhancements introduced in Proxmox 9.0, is it now recommended to use these built-in SDN features to separate Ceph network traffic, rather than relying on traditional VLANs configured through a switch or OPNsense?

Hello, I am having trouble configuring the Vnet Firewall. I have set up a PoC with two hosts. There is one VM on each host, each of which has a service interface and another interface for the NAS. Two VLANs are configured, one for the service and another for the NAS. The intention is that the...

Hallo, einmal eine Anfrage an euch zu dem Problem mit CT (Container) im Proxmox, die ich habe! Ich komme einfach nicht weiter. Screenshot 2025-09-26 091126.png Die Netzwerk Einstellung vom VE Proxmox des Server Master! Screenshot 2025-09-26 091232.png Die SDN Einstellung Screenshot...

Hello, apologies if I miss anything obvious, haven't had to dig this far into things yet and am still finding my way around Proxmox. I have a datacenter with three hosts. SDN is configured with a really basic setup. No firewalls are active anywhere. Two hosts work fine, all VLANs are accessible...
