Abstract:
1. A method of operating a first packet network device, the method comprising: advertising, via link state advertisements to a third packet network device, a route to a second packet network device, the route comprising a link aggregation supported by the first packet network device; advertising, via traffic engineering advertisements to the third packet network device, individual bandwidth availability for a group of component links that are members of the link aggregation, the group comprising at least one component link receiving a first request including a first label to reserve bandwidth on a first member link, of the group of component links, for traffic directed toward the first packet network device from the third packet network device along a first label-switched path; reserving the bandwidth on the first member link; acknowledging the reservation by directing a second request toward the third packet network device, the second request indicating a second label to be used on the first label-switched path; and creating a first routing table entry instructing the first packet network device to accept packets labeled with the second label, swap the second label for the first label, and direct the label-swapped packets toward the second packet network device on the first member link.
