Abstract
Coexistence and migration of legacy and VXLAN networks may be provided. A first anchor leaf switch and a second anchor leaf switch may detect that they can reach each other over a Virtual Extensible Local Area Network (VXLAN) overlay layer 2 network. In response to detecting that they can reach each other over the VXLAN, the second anchor leaf switch may block VLANs mapped to the VXLAN's VXLAN Network Identifier (VNI) on the second anchor leaf switch's ports connecting to spine routers. In addition, the first anchor leaf switch and the second anchor leaf switch may detect that they can reach each other over a physical layer 2 network. In response to detecting that they can reach each other over a physical layer 2 network, the second anchor leaf switch may block Virtual Extensible Local Area Network (VXLAN) segments at the second anchor leaf switch.
