With　the　extensive　application　of　IPv6　protocol,　the　traditional　IPv4　routing　table　lookup　algorithms　no　longer　satisfy　the　need　of　routing　forward　in　the　IPv6　network　environment.　So　we　optimize　the　routing　table　lookup　algorithm　to　adapt　fir　IPv6　that　employs　Bloom　filters　to　realize　parallel　longest　prefix　match.　The　algorithm　efficiently　narrows　the　scope　of　the　search,　reduces　the　average　tune　of　hash　probe　per　lookup,　and　thereby　enhances　lookup　speed
