Abstract
A method for use in a system including an Ethernet Virtual Private Network (EVPN) core network and a VXLAN data plane, a first gateway device GW1 and a second gateway device GW2 operating in an all-active multihoming mode to interconnect the EVPN core network and VXLAN data plane, is described. The method includes establishing, by the second gateway device GW2, a VXLAN tunnel to a remote VTEP X before traffic is sent by the remote VTEP X and received by the second gateway device GW2, but after traffic is sent by the remote VTEP X and received by the first gateway device GW1. wherein the first and second gateway devices GW1 and GW2 use an anycast IP address as a source address for VTEP X.
