如图所示，使用Dynamips搭建网络环境，交换机间均为Trunk链路，SW1、SW2、SW3的管理IP分别为10.10.1.201/26、10.10.1.202/26、10.10.1.203/26。
|
|
|
2、配置要求：
|
|
|
在SW1、SW2、SW3上添加VLAN 10、VLAN 20，IP地址段分别为10.10.10.0/24和10.10.20.0/24。
|
|
|
配置SW1为VLAN 10的根网桥，SW2为VLAN 20的根网桥，实现链路的负载分担。
|
|
|
在SW1、SW2、R1和R2上配置OSPF路由协议，实现网络互通，Router-id使用管理IP和Loopback地址。配置Area 1为完全末梢区域，Area 100为NSSA区域，将R2的直连网段10.20.1.1重分发到OSPF区域。
|
|
|
为R1添加用户名benet，密码cisco，要求只有SW3可以登录。
|
|
|
验证SW3可以ping通R2的Loopback0地址，验证SW3可以远程登录到R1。
|
|
|
在SW1和SW2上配置HSRP，SW1是VLAN 1的活跃路由器，SW2是VLAN 1的备份路由器，虚拟IP为10.10.1.254，配置占先权和端口跟踪。
|
