MX250 with 3 ISP links and possible load balancing

[LeAnts]

Hi All,

i am new to Meraki and need some insight please..

we have a sinlge MX250 being deployed.. it has 2 internet interfaces (SFP) and we have 3 ISP connections. From i read i cannot use the GBE or SFP ports for internet connectivity.

What is the best way to connect all 3x ISPs to the internet interfaces?

Can i aggregate the internet 1 and 2 together and create a subinterfaces for each ISP link using vlan tagging for each ISP connection? alternatively what is the best option to configure?

additionally, if the above is possible, can i then configure load balancing accross all 3 ISP links?

thanks in adv

It's not possible to use more than 2 WAN uplinks on a Meraki MX, both in terms of physical ports and uplink configuration.

spill the beans @CptnCrnch ....whats in the pipeline?

@DarrenOC Just as posted by @GreenMan, 18.2 will bring "Multi-WAN (2 Active + 1 Backup)".

ah!  Thought we were going to see another new train of MX's 🙂

MX250 is limited to two WAN ports.  While you could connect a WAN link of some kind to a LAN port, this would be accessible only via static routes, so not useful in your case, I suspect.   Some other MX models, released more recently, provide > 2 WAN ports.   Within 18.2 firmware (current customer-facing beta) a third WAN port can now be used as a backup, should WAN1 and WAN2 fail.   See 18.2 section here: https://documentation.meraki.com/Firmware_Features/Security_and_SD-WAN_(MX%2CZ)_Features_Directory

cool thanks for the prompt responses.. think we will push for load balancing on wan1 and wan2 for now.. these are 1gb isp links.. the 3rd one is a 100mb so might just discard that for the time being as it is not really used anyways.
