Abstract: Embodiments of this application disclose a segment routing over internet protocol version 6 (SRv6)-based communication method and a related apparatus. A layer 2 gateway generates an Ethernet virtual private network instance (EVI) media access control (EVI-MAC route), where the EVI-MAC route includes an Ethernet virtual private network instance segment identifier (EVI SID), the EVI SID is an SRv6 SID applied for by an EVI from the layer 2 gateway, and a MAC address carried in the EVI-MAC route does not include a MAC address of each host in the EVI. The layer 2 gateway advertises the EVI-MAC route to a layer 3 gateway. After the layer 2 gateway advertises the EVI-MAC route to the layer 3 gateway, the layer 3 gateway does not receive a MAC address of a host from the layer 2 gateway.

Abstract: Provided is a solar panel. The solar panel includes a frame having an accommodation opening, a front plate located at one of two opposite sides of the frame, a back plate located at another one of the two opposite sides of the frame, and a cell. The accommodation opening is enclosed by the front plate, the back plate, and the frame to form an enclosed space, and the cell is disposed in the enclosed space.

Abstract: The invention provides a method for preparing lithium manganese iron phosphate, which includes the following steps: S1: mixing a manganese source and/or an iron source in solid phase to obtain a first mixture; S2: sintering the first mixture in solid phase at 300° C. to 1200° C. to obtain a manganese iron oxide (MnxFe1?x?y)mOn; S3: mixing the manganese iron oxide (MnxFe1?x?y)mOn with a lithium source, a phosphorus source, and optionally a manganese source and/or an iron source in solid phase to obtain a second mixture; and S4: sintering the second mixture in solid phase at 350° C. to 900° C. to obtain lithium manganese iron phosphate LiMnxFe1?x?yPO4, wherein 0?x?1, and 0?y?1. The method of the present invention can be used to prepare a lithium manganese iron phosphate material with high tap density, long cycle life, low costs, and high cost-effectiveness.
