1. A method for implementing location identity separation protocol multi-homing, which is applied to a multi-home edge device (XTR) in a location identity separation protocol L ISP network, the method comprises the following steps:

  • establishing communication connection with other multi-homing XTRs in the same multi-homing XTR set, wherein each multi-homing XTR in the same multi-homing XTR set corresponds to the same EID network segment;

    synchronizing local terminal identification (EID) states with other multi-homed XTRs through the communication connection, the EID states including a state where a routing location R L OC is reachable or unreachable to an EID network segment;

    when a position request message aiming at a target EID is received, according to the EID state of each multi-homing XTR in the same multi-homing XTR set, a target R L OC address which can reach the target EID is determined, and a response message carrying the target R L OC address is returned to position requesting equipment, wherein the target R L OC address is the R L OC address of the multi-homing XTR which can reach the target EID in the same multi-homing XTR set.
