实验拓扑
实验要求
1.Server1及5erver2是两种不同业务的服务器，分别处于两个vLA: 10及20。pc要求能够访向到server1及server2；
2，当网络正常时，PC1访问server1的流量走Router>SM1>SN3>Server1这条路径，并且往返路轻—致，而PC2访间
server2的流量则走Router>SW2 SW3>Server2这条路径并且也要求来回路径一致;
3.当SW1发生故障或者SW1连接Router的链路Down掉时，要求pc访问server1的流量能够自动切换到sw2，同样的当
sw2发生故障时，Pc访问server2的流量要能够自动切换到sw1;
4.SW1,SW2、5w3三台交换机构成一个二层环路，运行MSTP防止环路;
5.Sw1及sw2为汇聚交换机，server1和server2的网关在这两台设备上;
6.SW1 、 SW2及 Router运行O5PF ; SW1及SW2的RouteID分别为192.168.255.11及192.168.255.12,
Router的RouterID为192.168. 255.1
