【实验需求】
1.二层交换机根据拓扑配置VLAN，将接口加入对应的VLAN ;并配置链路聚合，将接口加入链路。
2.R2、R3之间配置OSPF,R3、R4、R5之间配置RIP版本2。
3.R1与R2之间配置静态路由及默认路由。
4.配置重分发，实现全网互通。
5.配置NAT，将服务器映射到外网接口G0/0/0上

验证：路由器查看路由表可以看见各自协议宣告的网段。
3. 外网配置静态路由。
[R2]ip route-static 192.168.1.0 255.255.255.0 192.168.2.1
[R1]ip route-static 0.0.0.0 0.0.0.0 192.168.2.2
4. 配置重分发，实现全网互通。
[R2]ospf 1
[R2-ospf-1]import-route static
[R2-ospf-1]import-route direct
[r3-ospf-1]rip 1
[r3-rip-1]import-route ospf 1
[r3]ospf 1
[r3-ospf-1]import-route rip 1
验证：全网可以互通
配置NAT。
[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]nat server protocol tcp global 192.168.2.10 www inside 192.168.6.1 www
验证：可以通过映射的接口访问到192.168.6.1www服务器。
