（）即通用路由封装协议，是对某些网络层协议（如和）的数据报进行封装，使这些被封装的数据报能够在另一个网络层协议（如）中传输

一．实验拓扑

ip route 192.168.1.0 255.255.255.0192.168.4.1

三.检查结果

R1:

1.查看路由表：

r1#show ip route

Codes: C - connected, S - static, I - IGRP,R - RIP, M - mobile, B - BGP

Gateway of last resort is 61.130.130.2 tonetwork 0.0.0.0

    61.0.0.0/30 is subnetted, 1 subnets

C      61.130.130.0 is directly connected, FastEthernet0/0

C   192.168.1.0/24 is directly connected, FastEthernet0/1

S   192.168.2.0/24 [1/0] via 192.168.4.2

C   192.168.4.0/24 is directly connected, Tunnel10

S*  0.0.0.0/0 [1/0] via 61.130.130.2

2.查看tunnel接口

r1#show interface tunnel 10
