Abstract: Aspects of the embodiments are directed to systems, methods, and network elements executing instructions stored thereon. Aspects are directed to, for each spine node connected to a leaf node network element, identifying a spine router identifier, identifying a multicast group address, computing a plurality of hash values based on a hash function using the spine router identifier and the multicast group address, identifying a root spine node based on a highest hash value from the plurality of hash values; and transmitting an IS-IS message to root spine node indicating election of spine node as the root spine node.

Abstract: In one aspect, a method includes discovering, by a first network router in a network of routers associated with a provider network, a network address translation service available at one or more second network routers, and selecting the network address translation service at one of the one or more second network routers, the network address translation service allowing the first network router to remain on a default Multicast Distribution Tree (MDT) while at least a number of the one or more second network routers receive data flows over a data MDT.
