被认证⽅配置

[R1]interface s4/0/0

[R1-Serial4/0/0]ppp pap local-user huawei password cipher huawei

第六步：CHAP认证

主认证⽅配置

[R5]aaa

[R5-aaa]local-user huawei password cipher huawei

[R5-aaa]local-user huawei service-type ppp

[R5]interface s4/0/0

[R5-Serial4/0/0]ppp authentication-mode chap

被认证⽅配置

[R2]interface s4/0/0

[R2-Serial4/0/0]ppp chap user huawei

[R2-Serial4/0/0]ppp chap password cipher huawei

第七步：HDLC封装

[R3]inter s4/0/0

[R3-Serial4/0/0]link-protocol hdlc

[R5]interface s3/0/0

[R5-Serial3/0/0]link-protocol hdlc

第⼋步：R1R2R3构建MGRE环境

R1配置

[R1]interface Tunnel 0/0/0

[R1-Tunnel0/0/0]ip address 10.1.1.1 24

[R1-Tunnel0/0/0]tunnel-protocol gre p2mp

[R1-Tunnel0/0/0]source 15.1.1.1

[R1-Tunnel0/0/0]nhrp network-id 100

R3配置

[R3]interface Tunnel 0/0/0

[R3-Tunnel0/0/0]ip address 10.1.1.3 24

[R3-Tunnel0/0/0]tunnel-protocol gre p2mp

[R3-Tunnel0/0/0]source s4/0/0

[R3-Tunnel0/0/0]nhrp network-id 100

[R3-Tunnel0/0/0]nhrp entry 10.1.1.1 15.1.1.1 register

第九步：R1R4配置GRE

R1配置

[R1]interface Tunnel 0/0/1

[R1-Tunnel0/0/1]ip address 20.1.1.1 24

[R1-Tunnel0/0/1]tunnel-protocol gre

[R1-Tunnel0/0/1]source 15.1.1.1

[R1-Tunnel0/0/1]destination 45.1.1.4

R4配置

[R4]interface Tunnel 0/0/1

[R4-Tunnel0/0/1]ip address 20.1.1.2 24

[R4-Tunnel0/0/1]tunnel-protocol gre

[R4-Tunnel0/0/1]source 45.1.1.4

[R4-Tunnel0/0/1]destination 15.1.1.1

第⼗步：书写RIP路由

MGRE环境下RIP路由配置

R1配置

[R1]rip 1

[R1-rip-1]version 2

[R1-rip-1]network 192.168.1.0

[R1-rip-1]network 10.0.0.0

注意：MGRE环境下RIP需要开启伪⼴播和关闭⽔平分割

[R1]interface Tunnel 0/0/0

[R1-Tunnel0/0/0]nhrp entry multicast dynamic // 开启伪⼴播

[R1-Tunnel0/0/0]undo rip split-horizon // 关闭⽔平分割

R2配置

[R2]rip 1

[R2-rip-1]version 2

[R2-rip-1]network 192.168.2.0

[R2-rip-1]network 10.0.0.0

R3配置

[R3]rip 1

[R3-rip-1]version 2

[R3-rip-1]network 192.168.3.0

[R3-rip-1]network 10.0.0.0

GRE环境下配置

R1配置

[R1]rip 1

[R1-rip-1]version 2

[R1-rip-1]network 20.0.0.0

R4配置

[R4]rip 1

[R4-rip-1]version 2

[R4-rip-1]network 20.0.0.0

[R4-rip-1]network 192.168.4.0
