Question in regards to spine/leaf topology QinQ Termination.

[Li]

Hi all,

Based on the lab setup instructions,we need to use a linux dhcp server and enable QinQ tagging on an interface for it to listen to double tagged packets going to the dhcp server coming from dhcpl2relay service on AGG switch. 

Instead of using a linux interface, is there a way to configure QinQ termination on the AGG switchport where the BNG (DHCP server) is suppose to connect? 

Something similar to that syntax? 

e.g.

outer-tag is 101 and inner-tag is 200

"switch": {

            "basic": {

                "locations": ["of:0000000000000202/1"],

                "innerVlan": 200,

                "outerVlan": 101,

                "outerTpid": "0x88a8" or "0x8100"

            }

Hi,

There are a few documents about double vlan termination in this folder.
But please note that we are about to merge a code that will disable this feature. We will re-implement it as part of the SEBA BNG brigade.

Thanks,

Charles,

Ok, yes BNG access interface should do the QinQ and trap packets on capture SAP. Thanks will take a look at the documents.
