    Abstract: In one example, a method includes receiving, by a first network device, a route advertisement message including an attribute for upstream allocation specifying a plurality of next hops of a second network device for reaching a network destination, a plurality of forwarding semantics describing forwarding actions and respective attributes of the plurality of next hops, and a field indicating whether the attribute is provided for downstream allocation or upstream allocation. The method includes in response to determining, by the network device, that the field indicates the attribute is provided for upstream allocation: installing, by the network device and based on the forwarding semantics, next hops, forwarding actions, and the next hop attributes; and applying based on the forwarding information, the forwarding actions to network traffic received by the network device and destined for the network destination when forwarding the network traffic to one or more of the plurality of next hops.

    Abstract: A device may receive first topology information from a first network device of a network, and may receive second topology information from a second network device of the network. The device may assign a first BGP-LS identifier to the first network device, and may associate the first topology information with the first BGP-LS identifier. The device may assign a second BGP-LS identifier to the second network device, and may associate the second topology information with the second BGP-LS identifier. The device may store the first topology information, as a first route, based on the first BGP-LS identifier, and may store the second topology information, as a second route, based on the second BGP-LS identifier. The device may select the first route or the second route as a primary route, and may utilize the primary route to control routing of traffic through the network.

    Abstract: In one example, a management component executing on a single-chassis network device configures a virtual node with an abstract fabric interface having, as a destination address, identifiers of packet processors (e.g., PTFE-IDs) assigned to the virtual node on the other end of the abstract fabric interface. The management component of the single-chassis network device pre-creates an underlay network by using the fabric links at the packet processor. When the management component creates and connects an abstract fabric interface on the virtual nodes, the management component forms an overlay network and attaches the overlay network to the underlay network, e.g., by programming the forwarding plane packet processor, to connect the virtual nodes. However, users of the network device, external devices, and routing protocols will not view the abstract fabric interface as an overlay interface, but as a regular Ethernet interface (e.g., a Gigabit Ethernet interface).

    Abstract: In some examples, a method includes receiving, by a first network device, a private label route message from a second network device, the private label route message specifying a private label as a destination, a route distinguisher of an egress network device for the private label, a context protocol next hop address that identifies a private Multiprotocol Label Switching (MPLS) forwarding layer, and a next hop for the private label, determining, by the first network device and based on the private label route message, a label stack having a plurality of labels to use for forwarding traffic to the next hop for the private label, and storing, in a context forwarding table associated with the private MPLS forwarding layer, a private label destination with the label stack as a next hop for reaching the private label.
