A first node propagates a packet toward a second node based on selection of a first routing path for routing the packet from the first node toward an intended destination node. The second node received the packet, determines that the packet cannot be delivered to the destination node via the first routing path, inserts a u-turn label into the packet, and returns the packet to the first node. The u-turn label indicates that the packet is being returned to the first node by the second node due to a condition preventing propagation of the packet toward the destination node using the first routing path. The first node receives the packet including the u-turn label, selects a second routing path for routing the packet toward the destination node, and propagates the packet toward the destination node based on the second routing path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for rapid rerouting of LDP packets","description":"A u-turn fast rerouting capability is provided.
