VLAN+VTP+STP+HSRP+ACL+NAT+OSPF综合

wKiom1PJQK_zeJbOAAPfG9uWakA303.jpg 

如图所示,使用GN3搭建网络环境,交换机间均为Trunk链路。

2配置要求:

2.1

SW1SW2SW3上添加VLAN 10VLAN 20IP地址段分别为192.168.10.0/24192.168.20.0

2.2

配置SW1VLAN 10的根网桥,SW2VLAN 20的根网桥,实现链路的负载分担。

2.3

SW1SW2R1R2上配置OSPF路由协议,实现网络互通,Router-id使用管理IPLoopback地址。配置Area 1为完全末梢区域,Area 2NSSA区域,将R2的直连网段10.10.10.1重分发到OSPF区域。

2.4

R1设置密码benet,要求只有SW3以登录。

2.5

验证SW3可以pingR2Loopback0地址,验证SW3可以远程登录到R1

2.6

SW1SW2上配置HSRPSW1VLAN 10的活跃路由器VLAN20的备份路由,SW2VLAN 10的备份路由VLAN20的活跃路由,配置占先权和端口跟踪。

2.7

R2路由器是连接互联网的设备,现希望各区域主机访问Internet,则需要在R1上进行NAT配置,以此实现共享上网
