[R1]acl 2000
[R1-acl-basic-2000]rule 1 permit source any
[R1-acl-basic-2000]q
[R1]int s 4/0/0
[R1-Serial4/0/0]nat outbound 2000

R2：
[R2]acl 2000
[R2-acl-basic-2000]rule 1 permit source any
[R2-acl-basic-2000]q
[R2]int s 4/0/0
[R2-Serial4/0/0]nat outbound 2000

R3：
[R3]acl 2000
[R3-acl-basic-2000]rule 1 permit source any
[R3-acl-basic-2000]q
[R3]int s 4/0/0
[R3-Serial4/0/0]nat outbound 2000

R4：
[R4]acl 2000
[R4-acl-basic-2000]rule 1 permit source any
[R4-acl-basic-2000]q
[R4]int g 0/0/0
[R4-GigabitEthernet0/0/0]nat outbound 2000

1、R1和R5间使用PPP的PAP认证，R5为主认证方主

主认证方R5：
[R5]aaa
[R5-aaa]loca
[R5-aaa]local-user xiaomi password cipher 123456

[R5-aaa]local-user xiaomi service-type ppp
[R5-aaa]q
[R5]int s 3/0/0
[R5-Serial3/0/0]ppp authentication-mode pap

被认证方R1：
[R1]int s 4/0/0

2、R2与R5之间使用ppp的chap认证

主认证方R5：
[R5]aaa
[R5-aaa]local-user xiaomi password cipher 123456
Info: Add a new user.
[R5-aaa]local-user xiaomi service-type ppp
