    VXLAN & *sense with a cluster

    Hi all, I hope you are doing well. I’ve been researching for an answer or best practices but couldn’t really find a good solution or something straightforward. I have a 4 node cluster made up of small/tiny desktop PCs with each having a single NIC. Each PC connects directly to my home router...

    EVPN/VXLAN between nodes on different public networks

    Hi, We're trying to create a cluster of Proxmox nodes directly connected to Internet (public IP, inexpensive servers provided by OVH). No LAN. We have 2 nodes atm, one in France (n1) and one in Germany (n2). We're inexperienced with SDN. Our objectives are : - put all VMs on the same VNet /...

    [SOLVED] VXLAN SDN route/MAC address mismatch after migration

    Hi all! I've discovered an issue with VXLAN and routing, and I'm not sure if it's because my setup is wrong/weird or if it's a bug (possibly in the kernel). My setup is: Three nodes in a cluster, each node has an /32 address on loopback lo: vmhost0, vmhost1

    Datacenter Networking

    Hello PVE enthusiast, I am currently administering 4 Proxmox nodes and each one is siloed so there is no direct networking between nodes. the network setup on every node is the same (it's the basic bridged network that i saw in every PVE setup tutorial): These are the linux bridges that i have...

    Proxmox 8.0.4 SDN Questions

    Howdy everyone! I have a cluster where we want to use the VXLAN features of the SDN plugin (I know it is an experimental feature and we accept the associated risks). 1. Is there an API endpoint or other automation that others are using for this feature? 2. Are there any issues using SDN with HA?

    Integrating Proxmox SDN with existing SDN network

    I've been trying to integrate the Proxmox SDN into an existing vxlan network using IS-IS. This way we'll be able to use the different vnets across multiple clusters as well as bind that to a vlan to attach legacy devices. Our lab setup is using a route-reflector on a spine switch and 2 leaf...

    Incorrect MTU calculation when CT sending packets over bridged VXLAN port

    We have an overlay network (configured as described below) which worked fine on PVE6.4 but after migrating the containers to a PVE 7.2 node have noticed some odd behavior, with packets above a certain size being discarded by the vxlan interface, but only when sent from a container, VMs continue...
