Abstract:
1. A method of controlling transmission of link state messages of a flooding-based link-state routing protocol, the method comprising: establishing a link-state routing adjacency between a first router and a second router over a layer-two (L2) communication medium; sending one or more link state messages from the first router to the second router to synchronize link-state databases of the first router and the second router; receiving, with the first router, an inbound acknowledgement message from the second router that acknowledges receipt of the previously sent one or more link state messages in accordance with the flooding-based link state routing protocol, wherein the inbound acknowledgement message specifies a minimum packet interval for the first router to maintain between subsequent link state messages flooded to the second router; and flooding a plurality of link state messages from the first router to the second router over the L2 communication medium to communicate the link state messages, wherein the first router maintains at least the specified minimum packet interval between each of the plurality of link state messages when flooding the plurality of link state messages to the L2 communication medium.
