Abstract: A route advertisement method, where a second communication apparatus sends a BGP message to a third communication apparatus. The BGP message includes a first routing prefix, a first next-hop address, and a first color attribute. An address segment of the first routing prefix is a first address segment of the second communication apparatus, and the first color attribute indicates a first service intent. The second communication apparatus may further advertise a first SRv6 service route to a first communication apparatus. The first SRv6 service route includes a first SRv6 SID which is an address in the first address segment. The second communication apparatus and the first communication apparatus belong to different domains.
