The setting of one-arm routing
Step 1: divide the vlan first
Command:
In config (global) mode: vlan + vlan id (pure number (number range 2-1000))
Sw#conf t
Sw (config) # vlan 10pm 20
Sw (config-vlan) # e
Step 2: divide the interface into the corresponding vlan
Command:
1. Enter the API first: int + the number of the API to be entered (click the green dot to see it)
2. Config-if (interface mode) sw+tab + ac + tab + vlan + the number of the vlan you want to plan (which vlan does this interface belong to)
Sw (config) # int f1and3
Sw (config-if) # sw
Sw (config-if) # switchport a
Sw (config-if) # switchport access vlan 10
Sw (config-if) # int f1and2
Sw (config-if) # sw
Sw (config-if) # switchport a
Sw (config-if) # switchport access vlan 20
Step 3: open the port.
Command:
1. Enter the API first: int + the number of the API to be entered (click the green dot to see it)
2. Config-if (interface mode) sw + tab + mo+ tab + t+tab
Sw (config) # int f1and1
Sw (config-if) # sw
Sw (config-if) # switchport mo
Sw (config-if) # switchport mode t
Sw (config-if) # switchport mode trunk
Step 4: repackage and configure ip
Command:
1. The interface mode entered in config (global mode): int + the interface number to be entered (click on the green dot to see it)
2. Open the physical interface no shut
3. Return to config mode and enter the logical subinterface int + interface .1 (one starts from 1 in sequence)
4. Enter the number of the vlan to be encapsulated with en + tab + d + tab + selected encapsulation
5. Configure gateway ip add + configured gateway + subnet mask
R1 (config) # int f0bin0
R1 (config-if) # no shut
R1 (config-if) # e
R1 (config) # int f0plus 0.1
R1 (config-subif) # en
R1 (config-subif) # encapsulation d
R1 (config-subif) # encapsulation dot1Q 10
R1 (config-subif) # ip add 192.168.10.1 255.255.255.0
R1 (config-subif) # e
R1 (config) # int f0plus 0.2
R1 (config-subif) # en
R1 (config-subif) # encapsulation d
R1 (config-subif) # encapsulation dot1Q 20
R1 (config-subif) #
Only when encapsulated through the router can you communicate across network segments.
