Abstract: Provided are a packet forwarding method and system. a source node in a first SR-MPLS domain sends, based on an SR-Policy, a packet to a destination node in a second SR-MPLS domain, wherein an SR-Policy segment list of the packet includes a BSID, so that the packet passes through an SRv6 domain between the first SR-MPLS domain and the second SR-MPLS domain; After receiving the packet, the first border node replaces the BSID with the SRv6-Policy which destination address is the second border node, the second border node forwards the packet based on the SRv6-Policy, and after receiving the packet, the second border node decapsulates the IPv6 header and its extension header according to the behavior indication information in the SR-Policy, perform an MPLS label forwarding table lookup, so as to forward the packet within the second SR-MPLS domain, until the packet is forwarded to the destination node.

Abstract: Methods and devices for constructing a label and forwarding a label packet are provided. A node receives a message which carries a segment list and a segment list Identifier (ID) for identifying the segment list. The node constructs a label forwarding table according to the segment list and the segment list ID, and performs forwarding according to the label forwarding table; and/or the node maintains a mapping relationship between the segment list and the segment list ID.
