策略路由

​ 依据用户制定的策略进行路由选择的机制，优先于路由表

策略路由分类

​ ip单播策略路由：

​ 接口策略路由：在接口模式下配置并仅对本接口报文起作用

​ 本地策略路由：在系统模式下配置对本机产生的报文进行策略路由

​ ip组播策略路由：

策略路由：一般用于安全、负载分流，多数情况使用接口策略路由

​ 配置步骤：

​ 创建策略route-policy

​ 定义route-policy的if-match子句

​ 定义route-policy的apply子句

​ 使用/禁止本地策略路由

​ 使用/禁止接口策略路由

​ 配置命令：

​ acl advanced 3001 //扩展acl，表号从3000—3999

​ rule 0 permit ip source 192.168.3.0 0.0.0.255

​ quit

​ policy-based-route a1 permit node 10

​ if-match acl 3001

​ apply next-hop 200.200.200.1

​ quit

​ 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

​ 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）

​ int Vlan-interface 1

​ ip policy-based-route a1

​

交换机sw1配置：包括vlan以及ip的配置

[H3C]sysname sw1

创建VLAN

[sw1]vlan 2
[sw1-vlan2]vlan 3

为vlan创建ip

[sw1]int vlan 1
[sw1-Vlan-interface1]ip add 192.168.1.2 255.255.255.0
[sw1-Vlan-interface1]undo sh
[sw1-vlan3]int vlan 2

[sw1-Vlan-interface2]undo sh
[sw1-Vlan-interface2]int vlan 3
[sw1-Vlan-interface3]ip add 192.168.3.1 255.255.255.0
[sw1-Vlan-interface3]undo sh

端口加入vlan

[sw1]int g1/0/6
[sw1-GigabitEthernet1/0/6]port access vlan 2
[sw1-GigabitEthernet1/0/6]int g1/0/7
[sw1-GigabitEthernet1/0/7]port access vlan 3
[sw1-GigabitEthernet1/0/7]int g1/0/8
[sw1-GigabitEthernet1/0/8]port access vlan 3

测试：到目前为止三台pc：pc1与pc2以及server之间就可以通信了

路由配置

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

r1上配置静态路由和ospf

<r1>system-view
[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
[r1-ospf-1-area-0.0.0.0]net 202.202.202.0  0.0.0.3
[r1-ospf-1-area-0.0.0.0]net 200.200.200. 0  0.0.0.7

r2上配置ospf

<r2>system-view
[r2]ospf 1
[r2-ospf-1]area 0
[r2-ospf-1-area-0.0.0.0]net 0.0.0.0 255.255.255.255

r3上配置ospf

<r2>system-view
[r2]ospf 1
[r2-ospf-1]area 0
[r2-ospf-1-area-0.0.0.0]net 0.0.0.0 255.255.255.255

说明：

nat配置

配置acl，将需要转换的流量包含在acl2001中

[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

配置基于出接口的nat（easy-ip），将内网地址转换成r1的出口地址

[r1-acl-ipv4-basic-2001]int g0/0
[r1-GigabitEthernet0/0]port link-mode route
[r1-GigabitEthernet0/0]description link_to_tel
[r1-GigabitEthernet0/0]nat outbound 2001   
[r1-GigabitEthernet0/0]int g0/1`
[r1-GigabitEthernet0/1]port link-mode route
[r1-GigabitEthernet0/1]desc link_to_end
[r1-GigabitEthernet0/1]nat outbound 2001   

验证：在pc上可以ping外部的所有主机和接口

配置nat-server发布内网的telnet

[r1-GigabitEthernet0/1]nat server protocol tcp global 200.200.200.3 23 inside 19
2.168.3.250 23  
[r1-GigabitEthernet0/1]

验证：从pc1 ping 202.202.0.1

display nat session

验证

nat，在server上开启telnet

<server>system-view
[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

<pc3>telnet 200.200.200.3
login: admin
Password:
<server>
<server>

策略路由配置

[r1]acl advanced 3001 //扩展acl，表号从3000---3999
[r1-acl-ipv4-adv-3001]rule 0 permit ip source 192.168.3.0 0.0.0.255
[r1-acl-ipv4-adv-3001]quit

策略路由配置

[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]

验证：

从pc2访问外部走下一跳200.200.200.1

可以通过tracert 202.1.1.2跟踪

在r1上disp nat session

说明：模拟器上可能看不到效果
