Abstract: 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.

Abstract: An information reporting method includes after receiving a Border Gateway Protocol (BGP) flow specification (FS) rule, a network node obtains a status of implementing the BGP FS rule on the network node, where the status indicates that either the BGP FS rule is implemented on the network node or the BGP FS rule is not implemented on the network node. Then the network node sends the status to a server.

Abstract: This application provides an information processing method. A first communication apparatus is configured with a BGP EPE function, a BGP session is established between the first communication apparatus and a third communication apparatus, and no BGP session is established between the first communication apparatus and a second communication apparatus. In this case, the first communication apparatus may obtain, by using the third communication apparatus, a route advertised by the second communication apparatus. The next hop of the route is the second communication apparatus. After receiving the route, the first communication apparatus allocates a BGP peer SID, and stores a correspondence between the BGP peer SID and the next hop. When receiving a packet including the BGP peer SID, the first communication apparatus may forward the packet to the next hop based on the correspondence.

Abstract: A method and apparatus are provided. The method includes: a first network device sends route information of a destination network device, where the route information includes a destination address of the destination network device, a primary next-hop address, and a backup next-hop address, the primary next-hop address includes a common address of the first network device and a second network device, for example, a loopback address, and the backup next-hop address includes an address of the first network device, for example, an IP address of the first network device. By using this method, when a fault occurs in a connection between the second network device and the destination network device, another network device may directly send a packet to the first network device according to the backup next-hop address, to ensure normal packet forwarding.

Abstract: A packet processing method includes a first device that obtains a forwarding entry, where the forwarding entry includes a match entry and an action entry, and the match entry includes an identifier of one or more extension packet headers. The first device receives a first packet. The first device determines that the first packet includes an extension packet header that matches the match entry. The first device processes the first packet based on the action entry in response to determining that the first packet includes the extension packet header that matches the match entry.

Abstract: A first network device includes a processor and a memory having instructions stored thereon that, when executed by the processor, cause the first network device to: obtain a first virtual private network (VPN) route sent by a second network device. The first VPN route includes first identification information that uniquely identifies a first VPN instance in the second network device. The first network device is also caused to generate a second VPN route according to a second VPN instance accessing a third network device and the first VPN route. The second VPN route carries second identification information and routing information of the first VPN route. The second identification information uniquely identifies the second VPN instance in the third network device. The first identification information is different from the second identification information. The first network device is further caused to send the second VPN route to the third network device.
