Allow VLAN filtering based on L2VPN termination

[TheNetworkGuy]

NetBox version

v3.3.9

Feature type

New functionality

Proposed functionality

Allow (API) filtering VLAN's based on L2VPN termination. Currently i can filter VLAN's based on description, ID etc. But not with their corresponding VXLAN VNI identifier.

If this functionality is already present in a different way (get all L2VPN's with linked VLAN's) then that would also fulfill our use-case.

Use case

This would allow us to get a list of all VLAN's which would be active in our VXLAN environment with the API call "L2VPN_termination__n='null'".

Database changes

No DB change required

External dependencies

No new external dependencies.

To comment on this issue, maybe we are trying to filter the wrong way around. Instead of filtering on the VLAN object we can also perform a query on the L2 Terminations object:

I've extended this functionality to device & VM interfaces as well in 4bfc3bf.
