路由交换技术实验二：路由选择

配置命令：

AR1：SYS
int GigabitEthernet 0/0/0
ip address 172.16.1.1 24
Q
int GigabitEthernet 0/0/1
ip address 172.16.2.1 24
q
int LoopBack 0
ip address 172.16.10.1 24
Q
ip route-static 172.16.3.0 24 172.16.1.2 preference 60
ip route-static 172.16.20.0 24 172.16.1.2 preference 60
ip route-static 172.16.4.0 24 172.16.2.2
ip route-static 172.16.20.0 24 172.16.2.2
AR2：SYS
int GigabitEthernet 0/0/0
ip address 172.16.1.2 24
Q
int GigabitEthernet 0/0/1
ip address 172.16.3.1 24
q
ip route-static 172.16.20.0 24 172.16.3.2
ip route-static 172.16.10.0 24 172.16.1.1
AR3：SYS
int g0/0/0
ip address 172.16.2.2 24
q
int GigabitEthernet 0/0/1
ip address 172.16.4.1 24
q
ip route-static 172.16.20.0 24 172.16.4.2
ip route-static 172.16.10.0 24 172.16.2.1
AR4：SYS
int GigabitEthernet 0/0/0
ip address 172.16.3.2 24
Q
int GigabitEthernet 0/0/1
ip address 172.16.4.2 24
q
int LoopBack 0
ip address 172.16.20.1 24
Q
ip route-static 172.16.1.0 24 172.16.3.1
ip route-static 172.16.10.0 24 172.16.3.1
ip route-static 172.16.2.0 24 172.16.4.1 preference 60
ip route-static 172.16.10.0 24 172.16.4.1 preference 60
注意：
1.注意配置AR2,AR3,lo静态路由，要不然两个lo口不能通，实验无法成功
