Does Meraki MX Series supports multiple WAN termination in single WAN port ?

[SouvikT]

Hi Community, 

I want to create a solution for one of my customers. They want to implement SDWAN in 1000+ branch locations. They currently hosting proprietary software in their own physical DC and Branches are using MPLS connections to access the software.

I want to propose Meraki MX appliances for their Brach Office as well as DC & DR. So, more than 30+ MPLS and ILL connections are terminating in their DC. My question is as there are no appliances with 30+ physical WAN ports in MX series devices, how can I terminate all those links in 2 boxes ?

The solution I can think of is using L2 switches I can create different VLANs for all links and terminate each VLANs and configure router-on-a-stick on a single WAN port in MX device. Is it a possible solution or WAN ports in MX series doesn't support 802.1Q protocol. If it is possible my next question is how I can load balance all the link through one port. 

Thanks & Regards,

Souvik

What a waste of money, wouldn't it be easier for everyone to have an MX inside the SD-WAN?

Customer has a migration planned in future.

Terminate all MPLS in a L3 switch stack and route to single ended MX in concentrator mode.  Use a separate enterprise edge firewall and that way the single ended MX can terminate VPNs from anywhere.

We have used this setup with up to three concurrent MPLS and 3 concurrent internet connections over the last few years and it works well.
