    Packet loss issue at VLAN SDN VNet.

    Hello, I have a problem that I'm using VLAN SDN zones and at almost every VNet it looks good. But one VNet has a problem with packet loss (ping between VMs at same VLAN at same / diferrent nodes). I have a stack with 4 nodes, connected via 2x 25Gbps LACP (DACs to nexus 9300 series). This is...

    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?

    Custom IPAM plugins - NIPAP

    Good day, is there perhaps a template/documentation/examples for implementing a custom IPAM for the ProxMox SDN side? I'm looking at for IPAM as we roll out the next steps of our network, so obviously the question comes in w.r.t. PVE not (yet) supporting...

    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...

    I have a 3 node cluster in my home lab. Each Node has a single NIC and all can access the WAN and the physical LAN ok. I'm struggling to set up a VNET or virtual network so that some of the VMs/LXCs can exist on their own separate network but across the nodes. I've installed and configured SDN...

    SDN - Bug multiple VRFs

    Hello everybody, I noticed a bug when using multiple VRFs. When using the same exit-nodes on different vrfs but the primary is different, there is a deny route-map that is added in the MAP_VTEP_IN route-map for type 5 routes. So if vrf "red" has primary exit-node node 1 and vrf "blue" has...
