Abstract: A packet forwarding method is disclosed. The method includes: After an edge node in a trusted domain receives an SRv6 packet whose destination address is a BSID, the edge node may verify the packet based on a BSID in the packet and a destination field in an SRH of the packet. If the packet passes the verification, the edge node forwards the packet. If the packet fails the verification, the edge node discards the packet. Not only a node outside the trusted domain is required to access the trusted domain by using the BSID, but also the packet entering the trusted domain needs to be verified with reference to the target field in the segment routing header.
