A device-level redundancy protection method and system based on Link Aggregation Control Protocol (LACP), wherein the method includes: configuring same parameters for the Link Aggregation Group (LAG) on a first device (LAGP1) and the LAG on a second device (LAGP2), and transmitting an LACP Data Unit (LACPDU) message carrying the parameters to the LAG on a customer edge (LAGC). After receiving the LACPDU message, the LAGC adds physical links respectively connected with the LAGP1 and the LAGP2 into the same Aggregator on the customer edge (AGGC). The LAGP1 and the LAGP2 respectively add physical links connected with the LAGC into the Aggregator of themselves to form a virtual Aggregator (AGGV). The customer edge performs message interactions with a server via the AGGC and AGGV.
