Adding vPC to VXLAN | Network Direction vPC and VXLAN are both fantastic technologies. vPC gives us redundancy at the host, and VXLAN gives us layer 2 networks over a layer-3 fabric. The good news is that we can join the two! Now you can have the best of both worlds! But there are a few things that you need to know about first. For example, vPC breaks the pure spine/leaf architecture, as it needs a peer-link between a pair of leaf switches. In addition to this, the pair of switches need to look like a single switch to the rest of the fabric. To solve this, we need a secondary IP on our loopback interface. Remember to be careful with BGP peering and loopback interfaces. If there’s a peer-link failure, the loopback on the secondary will be shut down! Finally, you want to consider the backup routing SVI. This allows the peer-link to carry layer-3 traffic if the uplinks to the spine are down. vPC Videos:    • vPC   VXLAN Videos:    • VxLAN   Overview of this video: 0:00 Introduction 0:36 Review of vPC and VXLAN 4:06 Combining vPC and VXLAN 6:51 Best Practices 8:12 Backup Routing SVI LET'S CONNECT 🌏 null 🌏 https://twitter.com/NetwrkDirection 🌏 https://www.patreon.com/NetworkDirection 🌏 https://www.networkdirection.net/ #NetworkDirection
