Abstract: A packet advertisement method is implemented by a first network device. The packet advertisement method includes the first network device sending a first packet to a second network device advertising a route to the second network device. The first network device receives a second packet from the second network device in response to a first packet error. The second packet includes first indication information indicating the first packet error. The first network device determines, based on the first indication information, a route advertisement policy of a feature included in the first packet.

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.

Abstract: A packet transmission method, device, and system are disclosed, and pertain to the field of network technologies. The system includes a first network device in a VPLS network and a second network device in a VPWS network. The first network device determines, based on a destination address carried in a received first packet, a virtual port corresponding to the destination address in a VPLS instance of the first network device, and sends the first packet to a second VPWS instance in the second network device based on the virtual port, where the virtual port is used to indicate a first VPWS instance in the first network device, and the second VPWS instance and the first VPWS instance are VPWS instances used to bear a same service.

Abstract: An Ethernet virtual private network (EVPN) and a virtual private local area network (LAN) service (VPLS) active-active integration network includes a group of multi-homed provider edges (PEs) including a plurality of PEs on an EVPN side. The group of multi-homed PEs are all coupled to a same PE device on a VPLS side using inter-network pseudo wires (PWs). The inter-network PWs are configured to forward traffic between the group of multi-homed PEs on the EVPN side and the PE device on the VPLS side. The forwarding is performed based on specific preset rules using the inter-network PWs.

Abstract: This application provides a peer relationship management method and apparatus, a device, and a storage medium, and belongs to the field of network technologies. In this application, when a peer relationship between a first routing device and a second routing device is interrupted, routing entries received from the second routing device are not deleted. Services may be still processed, within a time range from a time at which the peer relationship is interrupted to a time at which the peer relationship is reestablished, by using the routing entries received from the second routing device.
