拓扑图中骨干链路有6条实验要求路由表尽量小则R1、R2、R4的两条环回需汇总为一条环回R5、R6各一条环回。
因此基于192.168.1.0/24的网段需向主机位借3位为网络位。网段划分如下
192.168.1.0/24 骨干链路 192.168.1.0/27 192.168.1.0/30 192.168.1.4/30 192.168.1.8/30 192.168.1.12/30 192.168.1.16/30 192.168.1.20/30 R1环回 192.168.1.32/27 192.168.1.32/28 192.168.1.48/28 R2环回 192.168.1.64/27 192.168.1.64/28 192.168.1.80/28 R3用户网段 192.168.1.96/27 R4环回 192.168.1.128/27 192.168.1.128/28 192.168.1.144/28 R5环回 192.168.1.160/27

R1-R5配置如下

[R5]ip route-static 192.168.1.8 30 192.168.1.17 内网全网通测试用R1去ping通R5的环回 可以ping通至此内外全网通了。
四、配置空接口防环 由于R1、R2、R4进行了路由汇总则可能会会出现路由黑洞和环路需要配置空接口进行防环。
[R1]ip route-static 192.168.1.32 27 NULL 0
[R2]ip route-static 192.168.1.64 27 NULL 0
[R4]ip route-static 192.168.1.128 27 NULL 0
五、配置优先级实现选路最佳
在R4与R5直接有两条直连链路分别是1000M与100M我们需要配置两条链路的优先级来实现当1000M链路出现故障时路由会自动选择100M链路进行数据传输。配置如下
[R4]dis ip routing-table protocol static 目标IP/掩码 协议 优先级 花销 标志 下一跳 接口
Destination/Mask Proto Pre Cost Flags NextHop Interface
192.168.1.0/30 Static 60 0 RD 192.168.1.9 GigabitEthernet0/0/0
192.168.1.4/30 Static 60 0 RD 192.168.1.13 GigabitEthernet0/0/1
192.168.1.32/27 Static 60 0 RD 192.168.1.13 GigabitEthernet0/0/1Static 60 0 RD 192.168.1.9 GigabitEthernet0/0/0
192.168.1.64/27 Static 60 0 RD 192.168.1.9 GigabitEthernet0/0/0
192.168.1.96/27 Static 60 0 RD 192.168.1.13 GigabitEthernet0/0/1
192.168.1.128/27 Static 60 0 D 0.0.0.0 NULL0
192.168.1.160/27 Static 60 0 RD 192.168.1.18 GigabitEthernet4/0/0Static 60 0 RD 192.168.1.22
通过查看R4的静态路由协议可以看出只有去往192.168.1.160/27的下一跳为192.168.1.22该接口在100M的链路上。我们只需修改该路由条目的静态优先级为61即可。
[R4]ip route-static 192.168.1.160 27 192.168.1.22 preference 61只修改R4上路由的优先级还不够还需将直连R5的路由优先级修改才可实现最路最佳。
查看R5 的静态路由协议可以看出R5去往R1、R2、R3、R4的下一跳均为192.168.1.21该接口也在100M的链路上。
[R5]dis ip routing-table protocol static 目的IP/掩码 协议 优先级 花销 标志 下一跳 接口
Destination/Mask Proto Pre Cost Flags NextHop Interface192.168.1.0/30 Static 60 0 RD 192.168.1.21 GigabitEthernet0/0/0Static 60 0 RD 192.168.1.17 GigabitEthernet0/0/1

[R5]ip route-static 192.168.1.128 27 192.168.1.21 pre 61
[R5]ip route-static 192.168.1.12 30 192.168.1.21 pre 61
[R5]ip route-static 192.168.1.96 27 192.168.1.21 pre 61
[R5]ip route-static 192.168.1.4 30 192.168.1.21 pre 61
[R5]ip route-static 192.168.1.32 27 192.168.1.21 pre 61
[R5]ip route-static 192.168.1.0 30 192.168.1.21 pre 61
[R5]ip route-static 192.168.1.64 27 192.168.1.21 pre 61
[R5]ip route-static 192.168.1.8 30 192.168.1.21 pre 61关闭1000M链路的接口进行测试如下
[R4]int g4/0/0
[R4-GigabitEthernet4/0/0]shutdown #关闭前跟踪从R1去往R5环回的路径如下
[R1]tracert 192.168.1.161traceroute to 192.168.1.161(192.168.1.161), max hops: 30 ,packet length: 40,pr
ess CTRL_C to break 1 192.168.1.6 50 ms 20 ms 192.168.1.2 120 ms 2 * 192.168.1.10 70 ms 30 ms 3 192.168.1.18 50 ms 30 ms 30 ms
##关闭后路径跟踪如下
[R1]tracert 192.168.1.161traceroute to 192.168.1.161(192.168.1.161), max hops: 30 ,packet length: 40,pr
ess CTRL_C to break 1 192.168.1.6 40 ms 20 ms 192.168.1.2 20 ms 2 192.168.1.10 30 ms 20 ms 10 ms 3 192.168.1.22 40 ms 30 ms 30 ms 清楚的看出关闭前路由走的是192.168.1.18的1000M链路关闭1000M接口后路由选择走的是192.168.1.22的100M链路。至此实现了选录最佳。
六、配置缺省路由实现公网通
要是内网可以访问公网则需要在R1-R5上配置去往公网ISP的路由但R1-R4并不知道去往ISP的IP这就需要进行缺省配置了。
R1-R5的缺省配置如下
[R1]ip route-static 0.0.0.0 0 192.168.1.2
[R1]ip route-static 0.0.0.0 0 192.168.1.6[R2]ip route-static 0.0.0.0 0 192.168.1.10[R3]ip route-static 0.0.0.0 0 192.168.1.14[R4]ip route-static 0.0.0.0 0 192.168.1.18
[R4]ip route-static 0.0.0.0 0 192.168.1.22
[R4]ip route-static 0.0.0.0 0 192.168.1.22 pre 61[R5]ip route-static 0.0.0.0 0 12.0.0.2
七、配置nat配置内网访问公网 R5作为内网去往ISP的边界路由我们需要在R5上进行NAT配置实现公网ip地址和私网ip地址之间的相互转换且华为设备所有NAT相关的配置都是在边界路由器的出接口上配置该端口转换属于PAT一对多类型也就是easy ip配置。
1...通过ACL抓取私网流量配置如下
[R5]acl 2000
[R5-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255 2... 在出接口上配置
[R5]int g0/0/2
[R5-GigabitEthernet0/0/2]nat outbound 20003...端口映射
[R5]int g0/0/2
[R5-GigabitEthernet0/0/2]nat server protocol tcp global current-interface 23 inside 192.168.1.1 23
Warning:The port 23 is well-known port. If you continue it may cause function failure.
Are you sure to continue?[Y/N]:yes
[R5-GigabitEthernet0/0/2]q
用pc1去访问ISP的环回 可以ping通。
八、做NAT SERVER发布内网服务器服务
实验要求R6 telnet R5的公有地址时实际登录到R1上则我们需要在R1上做telnet服务。
配置如下
[R1]telnet server enable
[R1]aaa
[R1-aaa]local-user vicky password cipher 111111 privilege level 15
[R1-aaa]local-user vicky service-type telnet
[R1-aaa]q
[R1]user-interface vty 0 4
[R1-ui-vty0-4]authentication-mode aaa
[R1-ui-vty0-4]q在R6上telnetR5如下 成功登录R1。
至此所有实验要求都完成了。
