A pod sits on a different subnet, so it has to be routed — and routing needs a gateway that doesn’t exist yet. Adding one changed what the fabric advertises, not what it is. https://otherthings.cloud/posts/vxlan-evpn-homelab-fabric/ Wed, 09 Sep 2026 00:00:00 +0000 https://otherthings.cloud/posts/vxlan-evpn-homelab-fabric/ I wanted to try OpenShift’s BGP EVPN support, so first I needed a fabric for it to join. One spine, two leaves, two hosts that ping each other with no L2 path between them — and the part I had wrong: FRR never creates the tunnel. https://otherthings.cloud/about/ Mon, 01 Jan 0001 00:00:00 +0000 https://otherthings.cloud/about/ Motohiro Abe — OpenShift and the networking underneath it, measured in a homelab and published with the failures left in.
