Topology design and IP Address planning

1. by R4 Conduct HDLC encapsulation 、PAP authentication 、CHAP Authentication and loopback configuration

[r4]int s4/0/0
（ Conduct HDLC encapsulation ）
[r4-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]:y
[r4-Serial4/0/0]ip address 14.1.1.2 24
（ Create account , The function of the account is to PPP encapsulation ）
[r4]int s3/0/0
[r4-Serial3/0/0]ppp authentication-mode pap
[r4-Serial3/0/0]ip add 24.1.1.1 24
[r4]aaa
[r4-aaa]local-user sss privilege level 15 password cipher 123456
Info: Add a new user.
[r4-aaa]local-user sss service-type ppp
[r4]int s4/0/1
[r4-Serial4/0/1]ppp authentication-mode chap
[r4-Serial4/0/1]ip add 34.1.1.2 24
[r4]aaa
[r4-aaa]local-user aaa privilege level 15 password cipher 123456
Info: Add a new user.
[r4-aaa]local-user aaa service-type ppp
[r4]int LoopBack 0
[r4-LoopBack0]ip address 4.4.4.4 24

testing

（ By default, both sides are PPP encapsulation , be in up state ）

[r4]int s3/0/0
[r4-Serial3/0/0]shutdown 
[r4-Serial3/0/0]undo shutdown
[r4]int s4/0/1
[r4-Serial4/0/1]shutdown 
[r4-Serial4/0/1]undo shutdown

（ see ）

2. Configure the private network router

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip address 192.168.1.1 24
[r1]int s4/0/0
[r1-Serial4/0/0]ip address 14.1.1.1 24
[r1-Serial4/0/0]link-protocol hdlc 
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]:y

[r2]int g0/0/0 
[r2-GigabitEthernet0/0/0]ip address 192.168.2.1 24 
[r2]int s4/0/0
[r2-Serial4/0/0]ip address 24.1.1.1 24
[r2-Serial4/0/0]ppp pap local-user sss password cipher 123456

[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]ip add
[r3-GigabitEthernet0/0/0]ip address 192.168.3.1 24
[r3]int s4/0/0
[r3-Serial4/0/0]ip address 34.1.1.1 24
[r3-Serial4/0/0]ppp chap user aaa
[r3-Serial4/0/0]ppp chap password cipher 123456

（ verification ）

3. Configure the computer IP Address

 

4. Configure the default route

[r1]ip route-static 0.0.0.0 0 14.1.1.2
[r2]ip route-static 0.0.0.0 0 24.1.1.2
[r3]ip route-static 0.0.0.0 0 34.1.1.2

（ verification ）

5. establish MGRE Environmental Science （MGRE Environmental Science --NBMA Network segment ）

[r1]int t0/0/0
[r1-Tunnel0/0/0]ip address 10.1.1.1 24
[r1-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r1-Tunnel0/0/0]source 14.1.1.1
（ start-up nhrp, As nhrp The service side ）
[r1-Tunnel0/0/0]nhrp entry multicast dynamic 
[r1-Tunnel0/0/0]nhrp network-id 100
[r2]int t0/0/0
[r2-Tunnel0/0/0]ip add 10.1.1.2 24
[r2-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r2-Tunnel0/0/0]source s4/0/0     
（ find 10.1.1.1 To register , Use its public ownership ip To register ）
[r2-Tunnel0/0/0]nhrp entry 10.1.1.1 14.1.1.1 register 
[r2-Tunnel0/0/0]nhrp network-id 100
[r3]int t0/0/0
[r3-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r3-Tunnel0/0/0]ip add 10.1.1.3 24
[r3-Tunnel0/0/0]source s4/0/0
[r3-Tunnel0/0/0]nhrp entry 10.1.1.1 14.1.1.1 register 
[r3-Tunnel0/0/0]nhrp network-id 100

（ see ）

（R2 ping 10.1.1.3 after ）

6. Declare （RIP）

[r1]rip 1 
[r1-rip-1]ver 2
[r1-rip-1]network 192.168.1.0
[r1-rip-1]network 10.0.0.0
[r2]rip 1
[r2-rip-1]ver 2
[r2-rip-1]network 192.168.2.0
[r2-rip-1]network 10.0.0.0
[r3]rip 1
[r3-rip-1]ver 2
[r3-rip-1]network 192.168.3.0
[r3-rip-1]network 10.0.0.0

（R1 Share routes to R2 and R3,R2 and R3 Routes are not shared between ）
（ Turn off horizontal split ）

[r1]int t0/0/0
[r1-Tunnel0/0/0]undo rip split-horizon 

Optimize ： Handwritten static routing

[r3]ip route-static 192.168.2.0 24 10.1.1.2
[r2]ip route-static 192.168.3.0 24 10.1.1.3

verification

7. Conduct NAT（ Will source IP Become public IP）

[r1]acl 2000
[r1-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255
[r1]int s4/0/0
[r1-Serial4/0/0]nat outbound 2000
[r2]acl 2000        
[r2-acl-basic-2000]rule permit source 192.168.2.0 0.0.0.255
[r2]int s4/0/0
[r2-Serial4/0/0]nat outbound 2000
[r3]acl 2000
[r3-acl-basic-2000]rule permit source 192.168.3.0 0.0.0.255
[r3]int s4/0/0 
[r3-Serial4/0/0]nat outbound 2000
