Abstract: In some implementations, a non-ingress node of one or more label-switched paths (LSPs) may identify a resource issue event. The non-ingress node may identify, based on identifying the resource issue event, one or more notification-requester stacks included in a data structure. The non-ingress node may generate one or more resource notification messages that each include a respective notification-requester stack of the one or more notification-requester stacks. The non-ingress node may send the one or more resource notification messages based on the one or more notification-requester stacks.

Abstract: In some implementations, a head Level 2 (L2) node of an intermediate system-intermediate system (IS-IS) flood reflection (FR) network may determine an end-to-end path from the head L2 node to a tail L2 node of the IS-IS FR network. The IS-IS FR network includes a plurality of L2 nodes and a plurality of FR clusters that each comprise a plurality of Level 1 (L1) nodes and a plurality of L1 and L2 (L1/L2) nodes connected by a plurality of L1 links. The head L2 node may send information associated with the end-to-end path to another node identified in the end-to-end path to cause a label switched path (LSP) to be established from the head L2 node to the tail L2 node, wherein the LSP traverses one or more L1 links within an FR cluster of the IS-IS FR network.

Abstract: A network device may receive a border gateway protocol (BGP) flow specification route associated with creation of an overlay network slice in a network, and may create a new routing instance based on the BGP flow specification route. The network device may associate interfaces defined by the BGP flow specification route with virtual private network (VPN) members, and may determine VPN parameters based on the BGP flow specification route. The network device may advertise the VPN parameters within the network to cause the network to generate the overlay network slice.
