Abstract:
1. A method comprising: designating an interface of a first network device associated with a peering link as a passive interface for which bandwidth reservations with a resource reservation protocol are unsupported, wherein the peering link couples the first network device within a first network to a second network device within a second network; upon designating the interface as a passive interface, calculating, by executing the resource reservation protocol within the first network device, an amount of bandwidth available on the peering link; and outputting a communication from the first network device to communicate the amount of bandwidth available on the peering link to a third network device within the first network to allow the third network device to account for the amount of bandwidth available on the peering link when computing a path within the first network that terminates at an exit point of the first network associated with the peering link.
