A method comprising: receiving , by a software defined networking, SDN, controller of a data center including one or more devices that each include one or more virtual routers configured thereon, from a Top-Of-Rack, TOR switch , a first multicast route and a second multicast route; wherein receiving the first multicast route and the second multicast route comprises receiving one or more router advertisements of the first multicast route and the second multicast route from the TOR switch; determining, by the SDN controller, from the one or more router advertisements, a first indication specifying that the first multicast route is designated with a first tunnel type corresponding to an assisted replication route type, and determining that the first multicast route is an assisted replication route in response to the first indication; and in response to determining that the first multicast route is the assisted replication route, adding, by the SDN controller, a first nexthop specified by the first multicast route to a list of nexthops for Broadcast, Unknown-Unicast, and Multicast, BUM, traffic; determining, by the SDN controller, from the one or more router advertisements, a second indication specifying that the second multicast route is designated with a second tunnel type that does not correspond to the assisted replication route type, and determining that the second multicast route is not the assisted replication route in response to the second indication; in response to determining that the second multicast route is not the assisted replication route, refraining from adding, by the SDN controller, a second nexthop specified by the second multicast route to the list of nexthops for BUM traffic; and provisioning , by the SDN controller, after adding the first nexthop, the list of nexthops at a virtual router of the one or more virtual routers. receiving , by a software defined networking, SDN, controller of a data center including one or more devices that each include one or more virtual routers configured thereon, from a Top-Of-Rack, TOR switch , a first multicast route and a second multicast route; wherein receiving the first multicast route and the second multicast route comprises receiving one or more router advertisements of the first multicast route and the second multicast route from the TOR switch; determining, by the SDN controller, from the one or more router advertisements, a first indication specifying that the first multicast route is designated with a first tunnel type corresponding to an assisted replication route type, and determining that the first multicast route is an assisted replication route in response to the first indication; and in response to determining that the first multicast route is the assisted replication route, adding, by the SDN controller, a first nexthop specified by the first multicast route to a list of nexthops for Broadcast, Unknown-Unicast, and Multicast, BUM, traffic; determining, by the SDN controller, from the one or more router advertisements, a second indication specifying that the second multicast route is designated with a second tunnel type that does not correspond to the assisted replication route type, and determining that the second multicast route is not the assisted replication route in response to the second indication; in response to determining that the second multicast route is not the assisted replication route, refraining from adding, by the SDN controller, a second nexthop specified by the second multicast route to the list of nexthops for BUM traffic; and provisioning , by the SDN controller, after adding the first nexthop, the list of nexthops at a virtual router of the one or more virtual routers. <EOS>
