  • 1.  Switching QinQ

    Hi all,

    Wondering what the correct way to pass QinQ traffic through a QFX without changing any of the inner or outer tags?

    SVLAN 100 CVLAN 1024 -> ge0/0/0 (QFX5120) ge/0/0/1 -> SVLAN 100 CVLAN 1024

    Can we just do trunks with the outer tag like so:
    set interfaces ge-0/0/0 unit 0 family ethernet-switching interface-mode trunk
    set interfaces ge-0/0/0 unit 0 family ethernet-switching vlan members 100

    set interfaces ge-0/0/1 unit 0 family ethernet-switching interface-mode trunk
    set interfaces ge-0/0/1 unit 0 family ethernet-switching vlan members 100

    or do I need to use ethernet-bridge or extended-vlan-bridge:
    set interfaces ge-0/0/0 flexible-vlan-tagging
    set interfaces ge-0/0/0 encapsulation extended-vlan-bridge
    set interfaces ge-0/0/0 unit 0 vlan-id 100

    is there any requirement to specify the CVLANs anywhere?
