VRRP+MSTP+OSPF实验

VRRP+MSTP实验

要求:

1.client1属于VLAN2(192.168.1.1/24) client2属于VLAN3 (192.168.2.1/24)

2.SW1SW2 SW3运行MSTP+VRRP,SW1作为1.0的根桥(同时作为网关VRRP为MASTER)SW2作为2.0 的根桥(同时作为网关VRRP为MASTER) 3.SW1SW2之间链路聚合

4.用R1的两个环回口模拟OABOSS服务器 IP分别为1.1.1.1,2.2.2.2 5.client1选择SW1到OABOSS ,client2选择SW2到OABOSS 6.SW1SW2 AR1之间运行OSPF协议

7.在AR1上起两个环回口模拟OABOSS服务器

8.CLIENT1和CLIENT2能相互通信并且二者都可以和OABOSS服务器通信

配置如下: AR1:
