The network device may receive, from the first neighbor network device, a multicast packet that includes a first BIER label associated with the network device. The network device may replace the first BIER label with a second BIER label associated with a second neighbor network device, and may transmit the multicast packet to the second neighbor network device. The second neighbor network device may be to tunnel the multicast packet to a third neighbor network device that supports BIER.

Abstract: A device receives topology data and path data associated with a network that includes network devices. The device determines planned bandwidths for new paths through the network based on the topology data and the path data, and ranks the new paths, based on the planned bandwidths, to generate a ranked list. The device selects information identifying a first new path from the ranked list, wherein the first new path includes a first planned bandwidth. The device determines whether the first new path can be provided via a single route through the network based on the first planned bandwidth, and identifies two or more routes through the network for the first new path when the first new path cannot be provided via the single route. The device causes the first planned bandwidth to be reserved by two or more of the network devices for the two or more routes.

Abstract: Techniques are described for facilitating the inclusion of a non-flexible-algorithm router to be included in flexible-algorithm path computations. For example, a flexible-algorithm router advertises information associated with a non-flexible-algorithm router to other flexible-algorithm routers in the network such that the flexible-algorithm routers may include the non-flexible-algorithm router when computing a path based on flexible-algorithm. During path computation, if the router determines that its next-hop router is the non-flexible-algorithm router, the router may configure additional forwarding information to cause the router to steer traffic to the non-flexible-algorithm router.
