GRE VPN——配置实验

1，按照图示配置IP地址

r1：

r2：

r3：

2，在R1和R3配置默认路由使公网区域互通

R1\]ip route-static 0.0.0.0 0 100.1.1.2 R3\]ip route-static 0.0.0.0 0 100.2.2.2 ### 3，在R1和R3上配置GRE VPN，使两端私网能够互相访问，Tunnel口IP地址如图,隧道双up： [R1-Tunnel0/0/0]tunnel-protocol gre [R1-Tunnel0/0/0]source 100.1.1.1 [R1-Tunnel0/0/0]destination 100.2.2.3 [R3-Tunnel0/0/0]tunnel-protocol gre [R3-Tunnel0/0/0]source 100.2.2.3 [R3-Tunnel0/0/0]destination 100.1.1.1 ping -a 192.168.3.1 192.168.3.3 PING 192.168.3.3: 56 data bytes, press CTRL_C to break Request time out Reply from 192.168.3.3: bytes=56 Sequence=2 ttl=255 time=40 ms Reply from 192.168.3.3: bytes=56 Sequence=3 ttl=255 time=30 ms Reply from 192.168.3.3: bytes=56 Sequence=4 ttl=255 time=30 ms Reply from 192.168.3.3: bytes=56 Sequence=5 ttl=255 time=20 ms --- 192.168.3.3 ping statistics --- 5 packet(s) transmitted 4 packet(s) received 20.00% packet loss round-trip min/avg/max = 20/30/40 ms ### 4，在R1和R3上配置RIPV2来传递两端私网路由 \[R1\]ip route-static 192.168.2.0 24 192.168.3.3 \[R3\]ip route-static 192.168.1.0 24 192.168.3.1 ping 192.168.1.1 PING 192.168.1.1: 56 data bytes, press CTRL_C to break Request time out Reply from 192.168.1.1: bytes=56 Sequence=2 ttl=127 time=20 ms Reply from 192.168.1.1: bytes=56 Sequence=3 ttl=127 time=30 ms Reply from 192.168.1.1: bytes=56 Sequence=4 ttl=127 time=30 ms Reply from 192.168.1.1: bytes=56 Sequence=5 ttl=127 time=20 ms --- 192.168.1.1 ping statistics --- 5 packet(s) transmitted 4 packet(s) received 20.00% packet loss round-trip min/avg/max = 20/25/30 ms
