Ethernet Virtual Private Network (EVPN) mechanisms are designed using bridge domains and integrated routing and bridging (IRB) capabilities that rely on data plane Media Access Control (MAC) learning to associate hosts to corresponding interfaces on provider edge (PE) routers. However, there are no existing mechanisms that allow for the ability to trigger seamless host mobility in the control plane when a Layer 3 (L3)/ Internet Protocol (IP) forwarding paradigm is used for a network environment. In order to address such issues, techniques are presented herein that provide for the ability to learn seamless host motion based only on an IP capability that leverages existing data plane constructs to trigger mobility such that a data plane redesign is not required. Through techniques presented herein, the IP security check punt path can be relied upon to learn host connectivity to a specific interface.
