In a mesh-based connected data center network architecture, a mechanism is provided to allow efficient delivery of IP multicast frames within the network. Described approaches avoid replication into VLANs (or SVIs) across the fabric by using the outer encapsulated tree to identify trees on which to replicate the traffic. Replication may be performed at the furthest point from the source (via routing or bridging). Also, multicast traffic may be distributed to dually connected (vPC) hosts on links from various network devices.

A leaf switch of a switch fabric includes multiple ports to connect with respective ones of multiple servers. Virtual local area networks (VLANs) are configured on the leaf switch. Dynamic creation of virtual ports is enabled on the leaf switch for at least one of the VLANs on an as needed basis. The leaf switch receives from a particular server connected to a corresponding one of the ports a notification message that a virtual machine is hosted on the particular server. Responsive to the notification message, the leaf switch dynamically creates a virtual port that associates the corresponding one of the ports with the at least one of the VLANs.
