Design with 3rd ethernet WAN uplink.

[JuanDavid]

Hi meraki community.

I have been designing a best solution for a customer, that needs a 3rd ethernet wan uplink. So i have some questions.

I have just one MX for site, and dont have HA configuration, by can´t add a spare.

1. The mx can have more of 2 ethernet wan uplink? How is that configuration?

2. If ia need configure flow preferences (internet traffic), there are some kind configuration that enable the prefered uplink in a VLAN? 

Thanks, i will be waiting for your help.

Hi Juan,

MX only has two WAN interfaces. The only option for a third WAN is LTE (but only as a backup).

Of course you can have flow preference...but only for two uplinks.

 Hi cptcrunch

thanks. the problem is i dont have MX(C) model, and my 3rd wan uplink, is needed if 2 first wan uplink fails. its a bakcup, but i cant use a doongle or a MX(C) model. by the way, this underlay is LTE, but using a router with this feature. And comercial team, think uses more than 2 wan uplink.

The max is 2 wan uplinks on the mx itself.

Flow preference is based on a ip or subnet of that vlan. 

You could connect a 3rd internet provider on a  lan port and make a default route for a vlan to that port, but you lose most mx functionality for that traffic.

Hi ww

thanks. Indeed, now i have a 3rd "wan" conections by a LAN and i am establishing the active route with a static route and the opticon "while host X responds to ping". And the autovpn (the real 2 wan uplinks), remains other routes as standby waiting happens the conditions in the static route.

As can you see, in the active route i'm not doing a VPN, only a simple MPLS(thats my underlay), and this design is nos SDWAN, and the commercial team, insist in keep call it as SDWAN.

maybe you know, if meraki support recognize a design like this this, as a functional in PBR? (i know thar i cant use this, like application routing)

What specifically are your 3 WAN circuits?  2 x Internet and 1 private MPLS?

Hi phillip

I have 1 internet, 1 mpls and 1 LTE, but using a router with this feature. And preseales team, didnt make a budget of MX(C) model or LTE Usb Doongle.

thats why i need meraki MX support a 3rd ethernet wan uplink 😞

Your proposed solution will work fine then.

Hi Phillip

Really thank you. 

With this document, i can check that the re-design proposed is supported by meraki.

Thanks for you all.
