1. A first routing device comprising:
a processor; and
a memory coupled to the processor and configured to store instructions that when executed by the processor, cause the first routing device to:
obtain an Internet Protocol version 6 (IPv6) packet, wherein the IPv6 packet comprises an IPv6 extension header, wherein the IPv6 extension header comprises preceding general indication information, and wherein the preceding general indication information comprises first information that instructs to process the IPv6 packet on a data plane of a routing device and to not send the IPv6 packet to a central processing unit (CPU); and
send the IPv6 packet to a next-hop routing device based on the first information.
