  • Patent number: 11240152
    Abstract: Techniques for exposing a subset of hosts on an overlay network, without exposing another subset of hosts on the overlay network, are disclosed. A component associated with an overlay network exposes a subset of hosts on the overlay network to components external to the overlay network. The component exposes the subset of hosts by distributing a mapping between (a) the hosts to-be-exposed and (b) the substrate addresses associated with the hosts. Alternatively, a component external to an overlay network exposes a subset of hosts on the overlay network to additional components external to the overlay network. The component exposes the subset of hosts by distributing a mapping between (a) the hosts to-be-exposed and (b) a substrate address associated with the particular component. In either embodiment, a mapping for hosts to-be-hidden is not distributed.
