Abstract
A route recursion control method includes a first network device that receives Border Gateway Protocol (BGP) routing information from a second network device. The BGP routing information includes a destination address, a next-hop address for the destination address, and attribute information. The attribute information indicates a manner of performing route recursion on the next-hop address by the first network device. The first network device determines, based on the attribute information, the manner of performing the route recursion on the next-hop address.
