Abstract
A first network device of a first tier of a network may receive a modified link state protocol (LSP) data unit, and may determine, based on the modified LSP data unit, whether an origin of the modified LSP data unit is executing the same algorithm as the first network device. The first network device may calculate a shortest-path spanning tree (SPT), and may set metrics to one for links associated with the first network device and the plurality of other network devices based on determining that the origin of the modified LSP data unit is executing a different algorithm than the first network device. The first network device may truncate the SPT to determine a flooding group, may select a member of the flooding group to flood the modified LSP data unit, and may cause the member to provide the modified LSP data unit to a second tier network device.
