Abstract: This application discloses a packet processing method and a Label Switching Router (LSR). The method includes receiving, by an Ingress LSR of a first Multiprotocol Label Switching (MPLS) tunnel, a first notification packet that is based on an IGP, where the first notification packet includes an Entropy Label Capability (ELC) flag indicating that the first Egress LSR has ELC. The method further includes, after learning from the first notification packet that the first Egress LSR has ELC, inserting a label into a first packet, to generate a second packet. The label forms an MPLS label stack, which includes, from bottom to top, a first EL, a first ELI, and a first TL. The method further includes sending the second packet to the first Egress LSR through the first MPLS tunnel.

Abstract: The application discloses a method and an apparatus for forwarding an MPLS data packet, which are used in an environment of hybrid networking of an SR network and a non-SR network. The method is as follows: when obtaining a to-be-sent MPLS data packet, a first SR router in an SR network determines whether a next-hop router supports an SR characteristic; the first SR router encapsulates the MPLS data packet into an IP tunnel when determining that the next-hop router does not support the SR characteristic, and sends an encapsulated MPLS data packet to the next-hop router to enable the encapsulated MPLS data packet to be forwarded, based on an IP routing table, to a second SR router. In this way, correct forwarding of an MPLS data packet is completed in an environment of hybrid networking of an SR router and a non-SR router.

Abstract: The present application provides a packet sending method and a network device. The packet sending method includes: receiving, by a network device, a first data packet; and if a MAC entry matching a destination MAC address of the first data packet is not found in a media access control MAC address table of the network device, sending, by the network device, the first data packet according to a forwarding behavior in a MAC default entry of the MAC address table. When the MAC entry matching the destination MAC address of the first data packet is not found, the network device does not need to flood the first data packet on all interfaces, but directly sends the first data packet according to the MAC default entry in the own MAC address table, thereby reducing a need for MAC address capacity in the network device, and not increasing unnecessary network traffic.

Abstract: This application discloses a packet processing method and an LSR. The method includes: receiving, by an Ingress LSR of a first MPLS tunnel, a first notification packet that is based on an IGP, where the first notification packet includes an ELC flag, which is used to indicate that the first Egress LSR has ELC; after learning from the first notification packet that the first Egress LSR has ELC, inserting a label into a first packet, to generate a second packet, where the label forms an MPLS label stack, which includes, from bottom to top, a first EL, a first ELI, and a first TL; and sending the second packet to the first Egress LSR through the first MPLS tunnel. According to the solutions of this invention, a Transit LSR of the first MPLS tunnel may perform load balancing when forwarding the second packet.
