Abstract
In one embodiment, a router includes processors and computer-readable non-transitory storage media coupled to the processors including instructions executable by the processors. The router may store at least one virtual prefix and an associated aggregation threshold. The router may register, with a mapping database of an overlay network, ownership of individual prefixes served by the router. The router may determine an amount of prefixes served by the router that are within an address space of the virtual prefix. The router may register, based on a determination that the amount of prefixes satisfies the aggregation threshold, ownership of the virtual prefix with the mapping database of the overlay network. The registration of the virtual prefix may cause ownership of one or more of the registered individual prefixes served by the router that are within the address space of the virtual prefix to be deregistered.
