 [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]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
