  • 1.  Selective QinQ on QFX

    Posted 08-29-2023 10:24

    Hi! 
    I have properly working QinQ on the QFX.  All C-VLANs from customers are double-tagged with S-VLAN. 
    Is it possible to pass one or many C-VLANs without double tagging? 
    For example, Vlans range 1-101 should be double tagged with ID 1000, but Vlan 102 must be a regular VLAN. 

    Thanks for your help.

    Here is my solution:
    et-0/0/32 and et-0/0/33  are  interfaces to the customer
    QinQ vlans 1-101 , regular vlan 102,    vlan on the router 1001

    VLAN102 is remaped to VLAN1001

    set interfaces et-0/0/32 flexible-vlan-tagging
    set interfaces et-0/0/32 encapsulation flexible-ethernet-services

    et interfaces et-0/0/32 description SRV1-vnic1
    set interfaces et-0/0/32 enable
    set interfaces et-0/0/32 flexible-vlan-tagging
    set interfaces et-0/0/32 encapsulation flexible-ethernet-services

    set interfaces et-0/0/32 unit 102 encapsulation vlan-bridge
    set interfaces et-0/0/32 unit 102 vlan-id 102
    set interfaces et-0/0/32 unit 102 input-vlan-map swap
    set interfaces et-0/0/32 unit 102 output-vlan-map swap
    set interfaces et-0/0/32 unit 102 family ethernet-switching vlan members v1001

    set interfaces et-0/0/32 unit 2100 encapsulation vlan-bridge
    set interfaces et-0/0/32 unit 2100 vlan-id-list 1-101
    set interfaces et-0/0/32 unit 2100 input-vlan-map push
    set interfaces et-0/0/32 unit 2100 output-vlan-map pop

    set vlans q-in-q interface et-0/0/32.2100
    set vlans q-in-q interface et-0/0/33.2100

    set vlans v1001 vlan-id 1001
