The third device determines, based on the first BIER information, the second BIER information, the attribute of the first device, and the attribute of the second device, a next hop to the edge BFR in the sub-domain.

Next hop determining method and apparatus

A first network device obtains first information. The first information indicates that a first link is faulty, and the first link is a link between any two network devices in a network system to which the first network device belongs. The first network device sends the first information to a second network device by using BGP, for example, sends a link fault message to the second network device by using BGP. The link fault message carries the first information. The second network device is a neighbor device of the first network device. The first network device determines an unreachable route in a routing table of the first network device based on the first information and a topology of the network system. A path corresponding to the unreachable route includes the first link. The first network device marks the unreachable route as invalid.

Route processing method and related device

In a packet processing method, when a tenant has different QoS requirements for different traffic, indication information that meets a QoS requirement for the traffic can be autonomously selected, and an SRv6 packet that includes the indication information is obtained and sent to a PE device in a provider network, so that the PE device in the provider network can be aware of the QoS requirement of the tenant for the traffic, to provide, for the traffic, a service that meets the QoS requirement.

Packet processing method and related device

Embodiments of this application disclose an information reporting method, an information processing method, and a device. According to the information reporting method, a network device obtains Border Gateway Protocol (BGP) information of a network device. The network device sends a BGP Monitoring Protocol (BMP) notification message to a first device, where the BMP notification message carries the BGP information of the network device.

Information reporting method, information processing method, and device

A BGP route identification method and apparatus are provided. A network device obtains a BGP route. The BGP route includes an autonomous system path attribute AS_PATH attribute, the AS_PATH attribute includes a first autonomous system number AS number, an AS number corresponding to an autonomous system that the network device is located in or manages is a second AS number, and the first AS number is equal to the second AS number. The network device determines, based on the first AS number and the second AS number, whether the BGP route is abnormal.

BGP route identification method, apparatus, and device

A method for updating route information includes a monitored network element establishes a Border Gateway Protocol (BGP) Monitoring Protocol (BMP) connection to a monitoring network element, and sends a first message to the monitoring network element when detecting a synchronization requirement of BGP route information, where the first message instructs the monitoring network element to update a BGP route information set, and the BGP route information set includes at least one piece of BGP route information. The first message indicates an update set, and the update set updates the BGP route information set.

Method and apparatus for updating route information, computer device, and storage medium

In a route processing method, a first network device obtains one or more routes having a same destination address, and including a first route. Slice information corresponding to the one or more ports is determined based on one or more ports that are on the first network device and that receive the one or more routes. The first network device sends an updated first route to a second network device, where the updated first route carries the slice information and the destination address. After a route is received, corresponding slice information is determined based on a port that receives the route, so that slice information supported by a path from a network device to a route starting device is determined. The determined slice information is carried when the route is forwarded, so that a network device on a route advertisement path can obtain the slice information supported by the entire path.
