Case sharing: basic networking configuration of QinQ

Configuration requirements

• company A Two branches of Site 1 and Site 2 Communicate through the operator network , The company uses VLAN by VLAN 10～70; company B Two branches of Site 3 and Site 4 It also communicates through the operator network , The company uses VLAN by VLAN 30～90.

• PE 1 and PE 2 Edge devices for operator networks , And both pass TPID The value is 0x8200 Network equipment of the operator .

• By configuring , Take advantage of VLAN 100 Make the company A Realize interworking between the two branches of , Take advantage of VLAN 200 Make the company B Realize interworking between the two branches of .

Configuration steps

(1) To configure PE 1

#  configure port GigabitEthernet1/0/1 by Trunk port , And allow VLAN 100 and VLAN 10～70 The message of .
<PE1> system-view
[PE1] interface gigabitethernet 1/0/1
[PE1-GigabitEthernet1/0/1] port link-type trunk
[PE1-GigabitEthernet1/0/1] port trunk permit vlan 100 10 to 70
#  configure port GigabitEthernet1/0/1 Of PVID by VLAN 100.
[PE1-GigabitEthernet1/0/1] port trunk pvid vlan 100
#  Open port GigabitEthernet1/0/1 Of QinQ function .
[PE1-GigabitEthernet1/0/1] qinq enable
[PE1-GigabitEthernet1/0/1] quit
#  configure port GigabitEthernet1/0/2 by Trunk port , And allow VLAN 100 and VLAN 200 The message of .
[PE1] interface gigabitethernet 1/0/2

(2) To configure PE 2

#  configure port GigabitEthernet1/0/1 by Trunk port , And allow VLAN 200 and VLAN 30～90 The message of .
<PE2> system-view

#  configure port GigabitEthernet1/0/1 Of PVID by VLAN 200.
[PE2-GigabitEthernet1/0/1] port trunk pvid vlan 200
#  Open port GigabitEthernet1/0/1 Of QinQ function .
[PE2-GigabitEthernet1/0/1] qinq enable
[PE2-GigabitEthernet1/0/1] quit
#  configure port GigabitEthernet1/0/2 by Trunk port , And allow VLAN 100 and VLAN 200 The message of .
[PE2] interface gigabitethernet 1/0/2
[PE2-GigabitEthernet1/0/2] port link-type trunk
[PE2-GigabitEthernet1/0/2] port trunk permit vlan 100 200
#  In the port GigabitEthernet1/0/2 Configure outer layer on VLAN Tag Of TPID The value is 0x8200.
[PE2-GigabitEthernet1/0/2] qinq ethernet-type service-tag 8200
[PE2-GigabitEthernet1/0/2] quit
#  configure port GigabitEthernet1/0/3 by Trunk port , And allow VLAN 100 and VLAN 10～70 The message of .
[PE2] interface gigabitethernet 1/0/3
[PE2-GigabitEthernet1/0/3] port link-type trunk
[PE2-GigabitEthernet1/0/3] port trunk permit vlan 100 10 to 70
#  configure port GigabitEthernet1/0/3 Of PVID by VLAN 100.
[PE2-GigabitEthernet1/0/3] port trunk pvid vlan 100
#  Open port GigabitEthernet1/0/3 Of QinQ function .

(3) Configure public network devices

Configure in the operator network PE 1 To PE 2 The device ports on the path between are allowed VLAN 100 and VLAN 200 The message carried VLAN Tag adopt , And these ports MTU It's worth at least 1504 byte .
