[r2]rip
[r2-rip-1]version 2
[r2-rip-1]undo summary
[r2-rip-1]network 192.168.2.0
[r2-rip-1]network 10.0.0.0
[r3]rip
[r3-rip-1]version 2
[r3-rip-1]undo su
[r3-rip-1]network 192.168.3.0
[r3-rip-1]network 10.0.0.0
[r4]rip
[r4-rip-1]v 2
[r4-rip-1]undo summary
[r4-rip-1]network 192.168.4.0
[r4-rip-1]network 10.0.0.0
打开伪广播关闭rip水平分割
[r1]interface Tunnel 0/0/0
[r1-Tunnel0/0/0]nhrp entry multicast dynamic
[r1-Tunnel0/0/0]undo rip split-horizon
[r2]interface tun 0/0/0
[r2-Tunnel0/0/0]undo rip split-horizon
[r3]interface t 0/0/0
[r3-Tunnel0/0/0]undo rip split-horizon
九、NAT配置

[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
[r2]acl 2000
[r2-acl-basic-2000]rule permit source 192.168.2.0 0.0.0.255
[r2]interface Serial 4/0/0
[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]interface Serial 4/0/0
[r3-Serial4/0/0]nat outbound 2000
[r4]acl 2000
[r4-acl-basic-2000]rule permit source 192.168.4.0 0.0.0.255
[r4-acl-basic-2000]q
[r4]interface GigabitEthernet 0/0/0
[r4-GigabitEthernet0/0/0]nat outbound 2000
