二、路由配置
1.sw1配置默认路由
[sw1-GigabitEthernet1/0/8]ip route-static 0.0.0.0 0.0.0.0 192.168.1.1
2.r1上配置静态路由和ospf
[r1]ip route-static 192.168.2.0 255.255.255.0 192.168.1.2
[r1]ip route-static 192.168.3.0 255.255.255.0 192.168.1.2
[r1]ospf 1
[r1-ospf-1]area 0
[r2-ospf-1-area-0.0.0.0]net 0.0.0.0 255.255.255.255
3.r2上配置ospf
[r2]ospf 1

[r2-ospf-1-area-0.0.0.0]net 0.0.0.0 255.255.255.255
4.r3上配置ospf
[r3]ospf 1
[r3-ospf-1]area 0
[r3-ospf-1-area-0.0.0.0]net 0.0.0.0 255.255.255.255
说明：
三、nat配置
[r1]acl basic 2001
[r1-acl-ipv4-basic-2001]rule 0 permit source 192.168.2.0 0.0.0.255
[r1-acl-ipv4-basic-2001]rule 5 permit source 192.168.3.0 0.0.0.255
[r1-acl-ipv4-basic-2001]rule 10 deny
[r1-acl-ipv4-basic-2001]int g0/0
[r1-GigabitEthernet0/0]port link-mode route
[r1-GigabitEthernet0/0]descriptionlink_to_tel
[r1-GigabitEthernet0/0]nat outbound 2001
[r1-GigabitEthernet0/0]int g0/1
[r1-GigabitEthernet0/1]port link-mode route
[r1-GigabitEthernet0/1]desclink_to_end
[r1-GigabitEthernet0/1]nat outbound 2001
[r1-GigabitEthernet0/1]nat server protocol tcp global 200.200.200.2 23 inside 19
2.168.3.250 23
[r1-GigabitEthernet0/1]
验证：从pc1 ping 202.202.0.1
display nat session
四、策略路由配置
[r1]acl advanced 3001
[r1-acl-ipv4-adv-3001]rule 0 permit ip source 192.168.3.0 0.0.0.255
[r1-acl-ipv4-adv-3001]quit
[r1]policy-based-route a1 permit node 10
[r1-pbr-a1-10]if-match acl 3001
[r1-pbr-a1-10]apply next-hop 200.200.200.1
[r1-pbr-a1-10]quit
[r1]policy-based-route a1 permit node 20 //空节点，即不匹配acl3001的流量都放行，正常查路由表
[r1-pbr-a1-20]quit
在接口vlan上应用策略路由（此处使用的是基于接口的策略路由）
[r1]int Vlan-interface 1
[r1-Vlan-interface1]ip policy-based-route a1
[r1-Vlan-interface1]
五、验证
1.验证nat，在server上开启telnet
[server]telnet server enable //默认开启
[server]local-user admin //创建用户admin
[server-luser-manage-admin]password simple benet //配置密码
[server-luser-manage-admin]service-type telnet //指定服务类型为telnet
[server-luser-manage-admin]authorization-attribute user-role level-3 //指定命令级别为3级
[server-luser-manage-admin]quit
[server]user-interface vty 0 //进入vty线路
[server-line-vty0]authentication-mode scheme //配置用户的认证方式
[server-line-vty0]protocol inbound telnet //支持telnet
[server-line-vty0]quit
在pc3上telnet服务器
