第一步先进行子网划分

拓扑图：

配置各设备的ip地址和环回

R1:
[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip add 192.168.1.1 30
[r1-GigabitEthernet0/0/0]int g0/0/1
[r1-GigabitEthernet0/0/1]ip add 192.168.1.9 30
[r1-GigabitEthernet0/0/1]int lo0
[r1-LoopBack0]ip add 192.168.1.33 28
[r1-LoopBack0]int lo1
[r1-LoopBack1]ip add 192.168.1.49 28

R2：
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip add 192.168.1.2 30
[r2-GigabitEthernet0/0/0]int g0/0/1
[r2-GigabitEthernet0/0/1]ip add 192.168.1.5 30
[r2-GigabitEthernet0/0/1]int lo0
[r2-LoopBack0]ip add 192.168.1.65 28
[r2-LoopBack0]int lo1
[r2-LoopBack1]ip add 192.168.1.81 28

R3：
[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]ip add 192.168.1.10 30
[r3-GigabitEthernet0/0/0]int g0/0/1
[r3-GigabitEthernet0/0/1]ip add 192.168.1.13 30
[r3-GigabitEthernet0/0/1]int g0/0/2
[r3-GigabitEthernet0/0/2]ip add 192.168.1.97 27

R4：
[r4]int g0/0/1
[r4-GigabitEthernet0/0/1]ip add 192.168.1.6 30
[r4-GigabitEthernet0/0/1]int g0/0/0
[r4-GigabitEthernet0/0/0]ip add 192.168.1.14 30
[r4-GigabitEthernet0/0/0]int g0/0/2
[r4-GigabitEthernet0/0/2]ip add 192.168.1.17 30
[r4-GigabitEthernet0/0/2]int g4/0/0
[r4-GigabitEthernet4/0/0]ip add 192.168.1.21 30
[r4-GigabitEthernet4/0/0]int lo0
[r4-LoopBack0]ip add 192.168.1.129 28
[r4-LoopBack0]int lo1
[r4-LoopBack1]ip add 192.168.1.145 28

R5：
[r5]int g0/0/1
[r5-GigabitEthernet0/0/1]ip add 192.168.1.18 30
[r5-GigabitEthernet0/0/1]int g0/0/0
[r5-GigabitEthernet0/0/0]ip add 192.168.1.22 30
[r5-GigabitEthernet0/0/0]int g0/0/2
[r5-GigabitEthernet0/0/2]ip add 12.0.0.1 24
[r5-GigabitEthernet0/0/2]int lo0
[r5-LoopBack0]ip add 192.168.1.161 27

R6：
[isp]int g0/0/0
[isp-GigabitEthernet0/0/0]ip add 12.0.0.2 24
[isp-GigabitEthernet0/0/0]int lo0
[isp-LoopBack0]ip add 1.1.1.1 24

配置缺省路由，防止环化

ip route-static 0.0.0.0 0 192.168.1.2

ip route-static 0.0.0.0 0 192.168.1.10

ip route-static 192.168.1.64 27 192.168.1.2

ip route-static 192.168.1.4 30 192.168.1.2

ip route-static 192.168.1.96 27 192.168.1.10

ip route-static 192.168.1.12 30 192.168.1.10

ip route-static 0.0.0.0 0 192.168.1.6
ip route-static 192.168.1.32 27 192.168.1.1
ip route-static 192.168.1.8 30 192.168.1.1
ip route-static 192.168.1.96 27 192.168.1.1
ip route-static 192.168.1.96 27 192.168.1.6

ip route-static 0.0.0.0 0 192.168.1.14

ip route-static 192.168.1.32 27 192.168.1.9

ip route-static 192.168.1.0 30 192.168.1.9

ip route-static 192.168.1.4 30 192.168.1.14

ip route-static 192.168.1.64 27 192.168.1.9

ip route-static 192.168.1.64 27 192.168.1.14

ip route-static 0.0.0.0 0 192.168.1.18

ip route-static 192.168.1.0 30 192.168.1.5

ip route-static 192.168.1.64 27 192.168.1.5

ip route-static 192.168.1.8 30 192.168.1.13

ip route-static 192.168.1.96 27 192.168.1.13

ip route-static 192.168.1.32 27 192.168.1.13

ip route-static 192.168.1.32 27 192.168.1.5

ip route-static 0.0.0.0 0 12.0.0.2

ip route-static 192.168.1.128 27 192.168.1.17

ip route-static 192.168.1.64 27 192.168.1.17

ip route-static 192.168.1.96 27 192.168.1.17

ip route-static 192.168.1.32 27 192.168.1.17

ip route-static 192.168.1.0 30 192.168.1.17

ip route-static 192.168.1.4 30 192.168.1.17

ip route-static 192.168.1.8 30 192.168.1.17

ip route-static 192.168.1.12 30 192.168.1.17

接下来给R3配置DHCP
[r3]dhcp enable
[r3]ip pool 1
[r3-ip-pool-1]network 192.168.1.96 mask 27
[r3-ip-pool-1]gateway-list 192.168.1.97
[r3-ip-pool-1]dns-list 114.114.114.114 8.8.8.8
[r3-ip-pool-1]int g0/0/2
[r3-GigabitEthernet0/0/2]dhcp select global
然后PC1和PC2自动获取IP

因为R1--R5要访问R6的环回，所以在边界路由器R5上配置NAT
[r5]acl 2000
[r5-acl-basic-2000]rule
[r5-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255
[r5-acl-basic-2000]int g0/0/2
[r5-GigabitEthernet0/0/2]nat outbound 2000
此时R1—R5均可访问R6的环回

防环操作

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

r4与r5正常通过1000链路,故障时通过100兆链路

r4：

ip route-static 0.0.0.0 0 192.168.1.22 preference 61

r5：

ip route-static 0.0.0.0 0.0.0.0 12.0.0.2

ip route-static 192.168.1.0 255.255.255.252 192.168.1.21 pr 61

ip route-static 192.168.1.4 255.255.255.252 192.168.1.21 pr 61

ip route-static 192.168.1.8 255.255.255.252 192.168.1.21 pr 61

ip route-static 192.168.1.12 255.255.255.252 192.168.1.21 pr 61

ip route-static 192.168.1.32 255.255.255.224 192.168.1.21 pr 61

ip route-static 192.168.1.64 255.255.255.224 192.168.1.21 pr 61

ip route-static 192.168.1.96 255.255.255.224 192.168.1.21 pr 61

ip route-static 192.168.1.128 255.255.255.224 192.168.1.21 pr 61

R6 telnet R5的公有地址IP时，实际登录到R1
[r1]aaa
[r1-aaa]local-user xixi privilege level 15 password cipher 123456
[r1-aaa]local-user xixi service-type telnet
[r1-aaa]q
[r1]user-interface vty 0 4
[r1-ui-vty0-4]authentication-mode aaa

R5进行端口映射

[r5]int g0/0/1

[r5-GigabitEthernet0/0/1]nat server protocol tcp global current-interface 80 inside 192.168.1.1 80
