PPP comprehensive experiment

The experimental requirements

1、R5 by ISP, It can only be carried out IP Address configuration , All addresses are public IP Address
2、R1 and R5 Inter use PPP Of PAP authentication ,R5 Main certifier ;
R2 and R5 Used between PPP Of chap authentication ,R5 Main certifier ;
R3 and R5 Used between HDLC encapsulation .
3、R1/R2/R3 Build a MGRE Environmental Science ,R1 For the central site ;R1、R4 From point to point GRE.
4、 The entire private network is based on RIP Network wide accessibility .
5、 all PC Set up private IP As source ip, You can visit R5 Loopback .

The experiment begins

1. Match according to the drawing IP Address
   R1-R4 similar
   
   
   R5
   
   

Finished IP After the address , To connect , You can write a default route
[R1]ip route-static 0.0.0.0 0 15.0.0.2

2. R1 and R5 Inter use PPP Of PAP authentication ,R5 Main certifier ;R2 and R5 Used between PPP Of chap authentication ,R5 Main certifier ;R3 and R5 Used between HDLC encapsulation .

It can be seen that Huawei equipment adopts PPP agreement
3. First in ISP Master certification PPP Authentication configuration ：
[ISP-aaa]local-user r1 password cipher 123456
[ISP-aaa]local-user r1 service-type ppp
[ISP-Serial3/0/0]ppp authentication-mode pap
And then in R1 Configure the authenticated party
[R1-Serial4/0/0]ppp pap local-user r1 password cipher 123456
If now ping, It does not mean that the authentication is successful . because PPP Create a one-time session , The previous session has been created , And the session created is not authenticated , So now we have to shutdown Here's the interface , Again ping, If it works , To prove PPP Authentication success .

CHAP Certifier ：
[ISP-aaa]local-user r2 password cipher 123456
[ISP-aaa]local-user r2 service-type ppp
[ISP-Serial3/0/1]ppp authentication-mode chap
Certified party ：
[R2-Serial4/0/0]ppp chap user r2
[R2-Serial4/0/0]ppp chap password cipher 123456
HDLC encapsulation （ Both sides must change the package type ）：
[R3-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y
[ISP-Serial4/0/0]link-protocol hdlc
Warning: The encapsulation protocol of the link will be changed. Continue? [Y/N]
:y
4. R1/R2/R3 Build a MGRE Environmental Science ,R1 For the central site ;R1、R4 From point to point GRE.
R1 Center point MGRE To configure ：
[R1]int t0/0/0
[R1-Tunnel0/0/0]ip add 192.168.5.1 24
[R1-Tunnel0/0/0]tunnel-protocol gre p2mp
[R1-Tunnel0/0/0]source 15.0.0.1
[R1-Tunnel0/0/0]nhrp network-id 100
R2、R3:
[R2]int t0/0/0
[R2-Tunnel0/0/0]ip add 192.168.5.2 24
[R2-Tunnel0/0/0]tunnel-protocol gre p2mp
[R2-Tunnel0/0/0]source s4/0/0
[R3-Tunnel0/0/0]nhrp network-id 100
R3-Tunnel0/0/0]nhrp entry 192.168.5.1 15.0.0.1 register
R4：
[R4]int t0/0/0
[R4-Tunnel0/0/0]ip add 192.168.6.2 24
[R4-Tunnel0/0/0]tunnel-protocol gre
[R4-Tunnel0/0/0]source 45.0.0.1
[R4-Tunnel0/0/0]destination 15.0.0.1
5. The entire private network is based on RIP Network wide accessibility
[R1]rip
[R1-rip-1]v 2
[R1-rip-1]net 192.168.1.0
[R1-rip-1]net 192.168.5.0
[R1-rip-1]net 192.168.6.0
On all routers both rip Declare
6. all PC Set up private IP As source ip, You can visit R5 Loopback [R1]acl 2000
[R1-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255
[R1]interface Serial 4/0/0
[R1-Serial4/0/0]nat outbound 2000
