METHOD AND APPARATUS FOR REALIZING MULTICASTING FLOW LOAD SHARING BASED ON EQUAL-COST MULTI-PATH ROUTE

摘要

Disclosed in the present invention are a method and an apparatus for realizing multicasting flow load sharing based on the equal-cost multi-path (ECMP) route. The method comprising the following steps: calculating an ECMP route identification in an obtained current ECMP route table when the ECMP route fails; according to the calculated ECMP identification in the current ECMP route table and the mapping relationship between the current ECMP route table and the global ECMP route table which are synchronized, determining a replacing ECMP route, wherein the global ECMP route table is the current ECMP route table during the system initialization; and transferring the multicasting flow of the failed ECMP route to the replaced ECMP route. By using the method and the apparatus for realizing the multicasting flow load sharing based on the ECMP route, a multicasting service oscillation caused by the failure of ECMP route between devices is avoided.
