    Abstract: This application provides a BIER multicast traffic statistics collection method, a device, and a system. The method includes: A first network device obtains a first BIER packet. The first network device performs traffic statistics collection on the first BIER packet based on multicast flow information, to obtain a traffic statistics collection result of the first BIER packet, where the multicast flow information is used to identify a multicast flow to which the first BIER packet belongs. The first network device sends the multicast flow information and the traffic statistics collection result of the first BIER packet to a controller.

    Abstract: A method for preventing a replay attack on a Segment Routing over Internet Protocol version 6 (SRv6) keyed hashed message authentication code (HMAC) verification. The method includes a network device receiving an SRv6 packet comprising anti-replay attack verification information. The network device performs anti-replay attack verification based on the anti-replay attack verification information. The network device performs HMAC hash computation on the SRv6 packet in response to the first SRv6 packet passing passes the anti-replay attack verification.

    Abstract: Embodiments of the present invention provide a network label allocation method, a device, and a system, which enable a local PE to distinguish packets from different remote PEs. The method includes: generating, by a local provider edge PE, a VPN label route for each remote PE, where VPN labels in VPN label routes of different remote PEs are different, and the remote PE and the local PE at least belong to a same VPN; and sending the VPN label route to the remote PE, so that the remote PE separately matches an IP address of the remote PE with a target device IP address in the VPN label route, and matches an import route target RT of each VRF of the remote PE with a route target RT in the VPN label route, a packet related to a successfully matched VRF.

    Abstract translation: 本发明的实施例提供一种网络标签分配方法，设备和系统，其使得本地PE能够区分来自不同远程PE的分组。 该方法包括：通过本地提供商边缘PE生成每个远程PE的VPN标签路由，其中​​不同远程PE的VPN标签路由中的VPN标签不同，远端PE和本地PE至少属于同一个 VPN; 并将VPN标签路由发送到远程PE，使远端PE分别与远端PE的IP地址和VPN标签路由中的目标设备IP地址匹配，并与远程PE的每个VRF的导入路由目标RT匹配 PE在VPN标签路由中具有路由目标RT，与成功匹配的VRF相关的数据包。

    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 method and network device for distributing Multi-Protocol Label Switching (MPLS) labels are provided by the present invention. The method for distributing the MPLS labels includes: a first device receives a Border Gateway Protocol (BGP) protocol message transmitted from a second device, wherein the BGP protocol message carries a service identifier of the second device; the first device establishes, according to the service identifier of the first device and the service identifier of the second device, a corresponding relationship between the first device and the second device; the first device distributes a MPLS label for the corresponding relationship. The present invention realizes that the MPLS labels are distributed for some type of the specific logical relationship between the two nodes in the BGP protocol, so that the network devices running the BGP protocol can efficiently obtain the MPLS label corresponding to the specific logical relationship.
