Abstract

Systems and methods that allow a multihomed gateway to monitor its membership in individual domains in an Ethernet Virtual Private Network (EVPN) Data Center Interconnect (DCI) Network, and issue withdrawals from multihoming groups associated with those domains based on this membership, are disclosed. According to embodiments, links between a local domain and a gateway, and between the gateway and a remote domain, can be monitored at the gateway. When the link between the gateway and a domain goes down the gateway may withdraw itself from any multihoming group associated with the domain to which the link has been lost.
