  • Routing information sending method, packet sending method, and related apparatus
    Patent number: 12250142
    Abstract: A method is applied to a network comprising a first area and a second area. A first node in the first area obtains aggregated routing information, where the aggregated routing information is obtained by aggregating a plurality of pieces of original routing information, the plurality of pieces of original routing information correspond to N nodes in a network segment, the N nodes in the network segment have a same flexible algorithm flex-algo, and the aggregated routing information carries an algorithm identifier used to indicate the flex-algo and a network segment identifier used to indicate the network segment. The first node sends the aggregated routing information to the second area, where the aggregated routing information is used to indicate a node in the second area to send a packet to the N nodes in the network segment based on the aggregated routing information.
