1. A method comprising:
receiving, at a first hub node of a hub and spoke network and from a first spoke of the hub and spoke network, a first network advertisement including a first border gateway protocol (BGP) large community associated with a first tenant node of the first spoke, wherein the first spoke is associated with the first hub node;
decoding, from a first portion of the first BGP large community, a first indication of a first virtual network instance (VNI) type associated with the first spoke;
decoding, from a second portion of the first BGP large community, a first address of a first tunnel endpoint associated with the first spoke;
storing, in a database associated with the first hub node, a mapping between the first VNI type and the first address of the first tunnel endpoint; and
sending, from the first hub node and to one or more second hub nodes of the hub and spoke network, the first network advertisement, wherein the one or more second hub nodes are associated with one or more respective spokes of the hub and spoke network.
