如图，只看红线内的，第一幅图左边省略掉，重点看第二图。

问题1：pc2可以通PC3,但不能通G1/0/3口 10.10.10.2/24,G3口应该是vlan1，不是所有vlan默认都和VLAN1通吗？还有G3口连接路由，不是用单臂路由的情况下是不是交换的G3口就不用做Trunk口？

问题2：假如想要PC2和PC3都能上网，静态路由该如何写,我对这里好模糊，什么目的地址，和下一跳，pc2要上网目的地址是10.10.11.0？这样写 ip rou 10.10.11.0 255.255.255.0 10.10.10.2(这里的下一跳是10.10.10.2还是路由的10.10.10.254)？

路由写回程路由：ip address 10.10.10.254/24.    IP ROU 10.10.11.0 255.255.255.0 10.10.10.2 

                                    再写一条到VLAN 20的：IP rou 10.10.12.0 255.255.255.0 10.10.10.2

以上写的路由对不对？如果对，这两条不如写成一条：IP rou 0.0.0.0 0.0.0.0 10.10.10.2。
