QinQ in combination with DHCP Option 82

  • 1.  QinQ in combination with DHCP Option 82

    Posted 11 days ago

    Good morning,

    I am a Juniper newbie, so forgive my lack of knowledge.

    I have a wholesale provider who is handing over my customer traffic as QinQ / S-VLAN- C-VLAN. This traffic arrives on one physical port.

    The S-VLAN, is customer type, i.e Home, Business, Enterprise
    The C-VLAN is a unique customer.

    The ultimate goal is that I am trying to use an EX3300 to add Option 82 information to the individual customer VLANs, so as to give the correct IP from radius depending on the customer VLAN. Is this possible?

    If not, can I strip the S-VLAN completely on ingress to the switch. Thus then say the home customers all are now single tagged VLANs within the switch?

    Any help appreciated

    I'm not sure I follow your scenario, so forgive me if this is off track.  But I think you are trying to configure option 82 on specific vlans on the switch which would be these instructions.

    https://www.juniper.net/documentation/en_US/junos/topics/topic-map/example-setting-up-dhcp-option82-no-relay.html#id-example-setting-up-dhcp-option-82-using-the-same-vlan

    The q-in-q additional vlan added would not need to come into play at all, just configuring the end client vlan that needs option 82 configured with our without forwarding of the dhcp request itself.
