Abstract
Embodiments of the invention may relate to a method for routing protocol area abstraction. The method may include electing an area leader from among network devices; generating, by the area leader, an area representation node identifier associated with the first area; distributing, by the area leader, the area representation node identifier to area edge devices; receiving, from the area edge devices, second area link state packets (LSPs); generating, by the area leader and using the second area LSPs, an area representation node LSP that includes the area representation node identifier and area neighbor adjacencies; and distributing, by the area leader, the area representation node LSP to a plurality of network devices in a second area of the network. In response to receiving a copy of the area representation node LSP, each of the network devices in the second area may advertise an adjacency to an area representation node.
