Abstract: A packet sending method and apparatus, a network device, a system, and a storage medium are disclosed in the field of communication technologies. An edge network device of a tier-1 carrier that has upgraded to an SRv6 network establishes a mapping relationship between a segment identifier and an MPLS label. After receiving a packet that carries an MPLS label and that is sent by a network device of a tier-2 carrier, the edge network device generates, based on the mapping relationship, a packet carrying a segment identifier. The packet carrying the segment identifier is forwarded in the SRv6 network of the tier-1 carrier.

Abstract: Embodiments of this application disclose a method for verifying an SRv6 packet. An egress node of an IPsec tunnel may receive an SRv6 packet, where the SRv6 packet is a packet encapsulated in an IPsec transport mode. The SRv6 packet includes an AH and at least one SRH. The SRv6 packet carries first indication information, where the first indication information indicates the egress node to perform AH verification on the SRv6 packet. A verification range of the AH verification includes the at least one SRH.

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.

Abstract: A packet processing method includes a first network device receiving a first packet, where the first packet includes a plurality of segment identifier (SID) lists, the plurality of SID lists include a primary SID list and at least one secondary SID list. The at least one secondary SID list includes a first secondary SID list, and the first secondary SID list is a backup of the primary SID list. The first network device processes the first packet based on the primary SID list. When a forwarding path indicated by a segment identifier list is faulty, data packet forwarding processing can still be implemented in the segment routing network.

Abstract: A routing information processing method and apparatus. The method includes a first network device determines a first segment identifier corresponding to a second network device and a first locator. The first network device determines a second segment identifier corresponding to a third network device and a second locator. The first network device sends routing information that includes the first segment identifier and the second segment identifier. A fourth network device advertises mirror routing information specific to the first network device, where the mirror routing information includes the second segment identifier or the second locator.
