Hw:单臂路由

 

1.R1与R2相同步骤：

[r1]display  current-configuration

[r1]interface GigabitEthernet0/0/0.1

[r1] dot1q termination vid 10

[r1]ip address 192.168.1.1 24

[r1] arp broadcast enable

[r1] dhcp select interface

[r1] dhcp server dns-list 8.8.8.8

2.LSW2:

[SW2]vlan  10   20

[SW2] interface GigabitEthernet0/0/1

[SW2]port link-type access

[SW2]port default vlan 20

[SW2]interface GigabitEthernet0/0/2

[SW2]port link-type access

[SW2]port default vlan 10

[SW2]interface GigabitEthernet0/0/3

[SW2]port link-type trunk

[SW2] port trunk allow-pass vlan 10 20

[SW2]interface GigabitEthernet0/0/4

[SW2] port link-type trunk

[SW2]port trunk allow-pass vlan 10 20

3.Lsw1:

[sw1] interface GigabitEthernet0/0/1

[sw1]port link-type access

[sw1]port default vlan 10

[sw1]interface GigabitEthernet0/0/2

[sw1] port link-type access

[sw1] port default vlan 20

[sw1]interface GigabitEthernet0/0/3

[sw1] port link-type trunk

[sw1] port trunk allow-pass vlan 10 20
