Abstract
A network node may receive an indication of a range of network address prefixes and a corresponding range of sequential identifiers. The network node may generate a policy for mapping respective network address prefixes, having ordered positions within the range of network address prefixes, to respective identifiers having corresponding ordered positions within the corresponding range of sequential identifiers. The network node may discover a device associated with a network address having a network address prefix at an ordered position within the range of network address prefixes. The network node may map, based on the policy, the network address prefix to an identifier having an ordered position within the corresponding range of sequential identifiers, wherein the ordered position within the corresponding range of sequential identifiers corresponds to the ordered position within the range of network address prefixes. The network node may advertise the mapping to one or more neighbor nodes.
