靜態路由及默認路由實驗配置
思科：
R1：
interface F1/0
ip address 192.168.1.1 255.255.255.255
no shutdown
interface F0/0
ip address 192.168.2.1 255.255.255.255
no shutdown
ip route 192.168.3.0 255.255.255.0 192.168.2.2
ip route 192.168.4.0 255.255.255.0 192.168.2.2

R2：
interface F0/0
ip address 192.168.2.2 255.255.255.255
no shutdown
interface F1/0

no shutdown
interface F1/0
ip address 192.168.4.3 255.255.255.0
no shutdown
ip route 0.0.0.0 0.0.0.0 192.168.3.2（使用默認路由，或者靜態路由：ip route 192.168.2.0 255.255.255.0 192.168.3.2 ip route 192.168.1.0 255.255.255.0 192.168.3.2 ）
