經典的靜態路由的實驗

1 ：網絡拓撲

實驗要求：使用 4 條靜態路由使得全網互通。

具體配置以下：

R0 路由器

r0#show running-config

hostname r0

interface Loopback0

ip address 5.5.5.5 255.255.255.0

interface FastEthernet0/0

測試：用 r0 路由器 ping r3 路由器上的 8.8.8.8

r0#ping 8.8.8.8

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 8.8.8.8, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 62/62/63 ms

r0#traceroute 8.8.8.8// 追蹤數據包的走向

Type escape sequence to abort.

Tracing the route to 8.8.8.8

1 1.1.1.2 31 msec 31 msec 32 msec

2 3.3.3.1 63 msec 47 msec 63 msec

3 3.3.3.2 63 msec 62 msec 62 msec

實驗總結：默認路由會給咱們帶來意想不到的好處。
