单臂路由的设置子接口设置IP脱标签

创建VLAN10 20，将PC分别加入到VLAN10 20
[sw2]vlan batch 10 20
[sw1]int e0/0/1
[sw1-Ethernet0/0/1]port link-type access
[sw1-Ethernet0/0/1]port default vlan 10
[sw1-Ethernet0/0/1]int e 0/0/2
[sw1-Ethernet0/0/2]port link-type access
[sw1-Ethernet0/0/2]port default vlan 20
[sw1-Ethernet0/0/2]int e0/0/3
[sw1-Ethernet0/0/3]port link-type trunk
[sw1-Ethernet0/0/3]port trunk allow-pass vlan 10 20

创建VLAN30 40，将PC分别加入到VLAN30 40
[sw2]vlan batch 30 40
[sw2]int e0/0/1
[sw2-Ethernet0/0/1]port link-type access
[sw2-Ethernet0/0/1]port default vlan 30
[sw2-Ethernet0/0/1]int e0/0/2
[sw2-Ethernet0/0/2]port link-type access
[sw2-Ethernet0/0/2]port default vlan 40
[sw2-Ethernet0/0/2]int e0/0/3
[sw2-Ethernet0/0/3]port link-type trunk
[sw2-Ethernet0/0/3]port trunk allow-pass vlan 30 40

R1上设置单臂路由（子接口设IP，去标签，ARP广播）
[R1]int g0/0/0.1
[R1-GigabitEthernet0/0/0.1]ip address 192.168.10.254 24
[R1-GigabitEthernet0/0/0.1]dot1q termination vid 10
[R1-GigabitEthernet0/0/0.1]arp broadcast enable
[R1-GigabitEthernet0/0/0.1]int g0/0/0.2
[R1-GigabitEthernet0/0/0.2]ip address 192.168.20.254 24
[R1-GigabitEthernet0/0/0.2]dot1q termination vid 20
[R1-GigabitEthernet0/0/0.2]arp broadcast enable
设置路由表

[R1]ip route-static 192.168.30.0 24 192.168.50.2
[R1]ip route-static 192.168.40.0 24 192.168.50.2

R2上设置单臂路由（子接口设IP，去标签，ARP广播）
[r2]int g0/0/0.2
[r2-GigabitEthernet0/0/0.2]ip address 192.168.40.254 24
[r2-GigabitEthernet0/0/0.2]dot1q termination vid 40
[r2-GigabitEthernet0/0/0.2]arp broadcast enable

[r2]int g0/0/0.1
[r2-GigabitEthernet0/0/0.1]ip address 192.168.30.254 24
[r2-GigabitEthernet0/0/0.1]dot1q termination vid 40
[r2-GigabitEthernet0/0/0.1]arp broadcast enable

[r2-GigabitEthernet0/0/0.2]int g0/0/1
[r2-GigabitEthernet0/0/1]ip address 192.168.50.2 24

设置路由表
[r2] ip route-static 192.168.10.0 24 192.168.50.1
[r2]ip route-static 192.168.20.0 24 192.168.50.1
