Abstract
This disclosure describes techniques for improved multicasting of source VLAN multicast traffic. For example, a method includes receiving, by a switch device within a data center of a leaf and spine network, multicast traffic from a multicast source; sending, by the switch device and to a border device within the data center that is communicatively coupled to a multicast rendezvous point external to the data center, a source-active routing message to indicate that the switch device is receiving multicast traffic from the multicast source; receiving, by the switch device and from the border device, a response routing message including an extended community that indicates whether there are any interested multicast receivers; and configuring, by the switch device, a forwarding engine of the switch device based on the extended community.
