Juniper Campus Fabric WAN Meraki MX Integration

We are deploying a network using Juniper Campus Fabric, with a Meraki MX appliance serving as both the perimeter firewall and the WAN router. Within the Juniper Campus Fabric architecture, we utilize a Service Block—this is where non-fabric devices, like the Meraki MX, connect to the fabric.

In this setup, every subnet that requires internet access is assigned a dedicated handoff VLAN. Each handoff VLAN is paired with its corresponding user VLAN inside a VRF. These VLANs and their VRFs are then mapped to sub-interfaces on the Service Block switch, which connects to the Meraki MX.

Here's where I'm hitting a challenge: the Meraki MX does not support sub-interfaces in the traditional Cisco router style (e.g., g0/0.1). I'm trying to understand if this kind of setup is possible with Meraki MX, or if instead, I should be using a trunk interface on the MX that carries multiple VLANs, with the MX configured using interface VLANs (i.e., routed VLAN interfaces).

You must use a trunk interface on the MX that carries multiple VLANs, with the MX configured using interface VLANs, since the MX does not support sub-interfaces.

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.

Please, if this post was useful, leave your kudos and mark it as solved.
