Abstract

A method, system, apparatus and machine-readable medium for transmitting a packet through a network to convey network topology is provided. The method includes the step of generating at least one link state protocol data unit (LSP) with a first identifier until reaching a maximum sequence number in a sequence assigned to a network device, represented by the first identifier. The method further includes the step of modifying the first identifier to produce a second identifier. The method also includes the step of generating at least one LSP with the second identifier, and with a sequence number that is less than or equal to the maximum sequence number in the sequence. The system for transmitting a packet through a network, to convey network topology, comprises the means for performing the above-mentioned method steps.
