Method for forwarding message in SRv6 network and related device

The invention discloses a method for forwarding a message in an SRv6 network. The method comprises the following steps: receiving the message; judging whether the destination address field corresponds to the local segment identifier or not, and if so, searching based on the destination address field to obtain a corresponding first Ad table; judging whether the value of the segment residual index is 0 or not, if not, executing a first processing behavior, and sending a loopback through a first loopback port; receiving a loopback completed message, and searching to obtain a corresponding second Ad table; judging whether the value of the segment residual index is 0 or not, and judging whether the PSP is enabled or not based on the configuration of the second Ad table; and selecting whether to execute a second processing behavior or not based on a judgment result, and then performing routing lookup forwarding on the processed message based on the updated destination address field. According to the method, multipl
