A routing information transmission method includes before forwarding a service traffic packet, a first network device receives first Border Gateway Protocol (BGP) routing information from a second network device to determine a first forwarding table entry based on a service identifier and an identifier of a first network slice that are in the first BGP routing information. The first forwarding table entry indicates to forward, to the second network device using the first network slice, the service traffic. When receiving the service traffic packet corresponding to the service identifier, the first network device determines the first network slice based on the first forwarding table entry, and then sends the service traffic to the second network device using the first network slice.
