Abstract (en)

[origin: WO2019229760A1] Methods and apparatuses for configuring a plurality of network elements in a data plane of a network are described. A network controller selects designated network elements. The number of designated network elements is strictly less than the number of all of the plurality of network elements in the network. The network controller configures each designated network element to include a Layer 3 forwarding table including a forwarding table entry for each network element from the plurality of network elements. The remaining network elements from the plurality of network elements are non-designated network elements. The network controller configures each non-designated network element to include a Layer 3 forwarding table including a default forwarding table entry having a designated network element as a next hop destination for traffic flows causing each of the non-designated network elements to forward all traffic associated with the plurality of traffic flows to the designated network element.
