Abstract
Embodiment provide recovering multicast data traffic during spine reload in software defined networks by identifying interfaces available between spine switches and a public network in a site; identifying Group Internet Protocol-outer (GIPo) addresses that handle multicast communications between endpoints associated together in a bridge domain, wherein the endpoints are connected via leaf switches in communication with the spine switches in a Clos topology; assigning each GIPo address to one virtual interface group (ViG) of a plurality of ViGs to generate GIPo-to-ViG mappings; distributing the GIPo-to-ViG mappings to the spine and leaf switches; assigning each ViG to one Interface as first ViG-to-Interface mappings; distributing the first ViG-to-Interface mappings to the spine and leaf switches and; when a number of available Interfaces changes, re-assigning each ViG to one currently-available Interface as second ViG-to-Interface mappings; and distributing the second ViG-to-Interface mappings to the spine switches and to the leaf switches.
