MX VLAN and Addressing Template for 1000 sites

[Jhunrik]

Greetings,

i have read multiple topics here regarding the Vlan and addressing templates and how to have unique subnets for each sites the problem is that when i bulk add all the existing sites the subnets are randomly assigned to random sites for example

Site1

data-10.16.1.0/25

guest-10.16.3.128/25

Site2

data-10.16.5.128/25

guest-10.16.6.128/25

Site1

data-10.16.7.128/25

guest-10.16.9.0/25

it is very important for us to assign a site with a specific subnet for its data and guest to easily identify that site for example:

Site1

data-10.16.1.0/25

guest-10.16.1.128/25

Site2

data-10.16.2.0/25

guest-10.16.2.128/25

Site1

data-10.16.3.0/25

guest-10.16.3.128/25

is there a way this can be achieved? right now i have to manually assign subnets to each site which defeats the purpose of the template.

I think you'll need to use a script to do this.  You'll need VLANs enabled, and you'll want to use this API:

@HodyCrouch will be able to give better advice.

I've changed my mind.  Use the Bulk network creation tool.

the way i see it is that this bulk network creation is meant for initial deployment of devices and not for existing networks and the sample csv file only has 1 vlan and i think this is only for the local page settings of the device.

@PhilipDAth has the right idea, in my opinion. We had to bulk create 250ish networks some months back, and I used a fairly simple PowerShell script to hit the API and update the VLANs after the networks were created. I used a script to create the networks and add them to our templates as well but that's not always necessary. Powerful stuff once you get the hang of it!
