    摘要: A method for implementing FRR comprising_starting up an upper layer protocol software to manage and configure a FRR route; an upper layer protocol software sending down a active next hop of the FRR; a driver writing an IP address of the FRR into an ECMP table and creating a software table to record correspondence between a FRR group and ECMP group; informing the driver of a prefix address of a subnet route and the index of the FRR group, and the driver finding the index of the ECMP group, and writing information of the subnet route and the index of the ECMP group into hardware; an upper layer protocol software informing the driver of the index of the FRR and an IP address of a new standby next hop; the driver looking up for the index of the ECMP group, and updating the next hop address of the ECMP group.
