Abstract: Methods of route control in a communications network are provided. In an example, routing information is received from a first router, the received routing information reporting at least one routing path between a first autonomous system and a second autonomous system. Next, a determination is made as to whether the reported routing path is superior to a previously known routing path. Filter instructions are sent to a given router instructing the given router not to report routing paths between the first autonomous system and the second autonomous system unless a routing path superior to one of the at least one reported routing path is received based on the determining step. In another example, filter instructions are received, from a given router, requesting a blockage of route reporting for routing paths between a first autonomous system and a second autonomous system which are inferior to a first routing path threshold.
