Embodiments of the present invention provide an address assignment method, a device, and a system. The method is applicable to a network having a broadband remote access server BRAS, where the BRAS is set with carrier grade net address translation CGN, the method including: detecting, by the BRAS, that the locally set CGN fails; receiving, by the BRAS, an access request sent by a terminal; and assigning, by the BRAS, a public IP address to the terminal. In the embodiments of the present invention, when the CGN fails, terminal traffic transfer is not required, thereby shortening terminal service recovery time when the CGN of the BRAS fails, and lowering costs. |
