Abstract
Techniques for implementing multicast messaging between spokes in a hub and spoke network are provided in the present disclosure. Multicast messages may be efficiently routed by creating separate multicast groups for upstream traffic from a source spoke to the hub (a “To Hub” group joined by the hub) and downstream traffic from the hub to spokes (a “From Hub” group joined by spokes interested in receiving multicast messages). A source spoke may send a multicast message encapsulated in a packet with the “To Hub” group address as the destination. Upon receipt, the hub may re-route the multicast message to spokes that have joined the “From Hub” group by encapsulating the original message in a packet with the “From Hub” group address as the destination.
