Protocol independent multicast sparse mode (PIM-SM) support for data center interconnect
Techniques are described for utilizing Protocol Independent Multicast Sparse Mode (PIM-SM) to transport BUM (broadcast, unknown unicast, and multicast) traffic in a Virtual Extensible LAN (VXLAN) underlay of a data center, where the BUM traffic is received on active-active, multi-homed Ethernet virtual private network (EVPN) interconnects between multiple physical data centers. For example, the techniques may readily be applied to support usage of PIM-SM where provider edge (PE) routers of the EVPN operate as gateways between the EVPN and the VXLAN spanning the data center interconnect.
