Radvd 將廣告傳送到錯誤的介面

Question

我有以下 radvd.conf 檔案：

interface eth0
{
        AdvSendAdvert on;
        MinRtrAdvInterval 30;
        MaxRtrAdvInterval 100;
        route 2000:e000:0:2::/64
        {
                AdvRoutePreference low;
        };
};

interface tap_tap
{
        AdvSendAdvert on;
        MinRtrAdvInterval 30;
        MaxRtrAdvInterval 100;
        prefix 2000:e000:0:2::/64
        {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };

        route 2000:e000:0:1::/64
        {
                AdvRouteLifetime infinity;
                AdvRoutePreference high;
        };

};

這個想法是有一個面向內部網路的 eth0 介面和一個可以透過 VPN 連接的 Tap 介面。在 eth0 介面上，我想通告路由，以便內部網路中的每個人都可以看到 VPN 用戶端，問題是 eth0 通告被其他介面（例如 eth1）接收，從而弄亂了整個路由：

        AdvManagedFlag off;
        AdvOtherConfigFlag off;

        AdvDefaultPreference medium;
        AdvSourceLLAddress on;

        route 2000:e000:0:2::/64
        {
                AdvRoutePreference low;
                AdvRouteLifetime 300;
        }; # End of route definition

}; # End of interface definition

        AdvManagedFlag off;
        AdvOtherConfigFlag off;
        AdvReachableTime 0;
        AdvRetransTimer 0;
        AdvCurHopLimit 64;
        AdvDefaultLifetime 300;
        AdvHomeAgentFlag off;
        AdvDefaultPreference medium;
        AdvSourceLLAddress on;

        route 2000:e000:0:2::/64
        {
                AdvRoutePreference low;
                AdvRouteLifetime 300;
        }; # End of route definition

}; # End of interface definition

奇怪的是，我在某些環境中成功地使用了完全相同的設置，由於某種原因，在某些環境中這種情況突然發生，有什麼我遺漏的嗎？

謝謝你！
