MX450 Internet redunduncy

[ChiragPatel]

Hi, I have MX450 with direct internet. I have L2 link to Datacenter with internet. How should I use / setup to use direct internet as primary link but when primary direct link fails I want internet traffic to failover to  use Datacenter link and internet from Datacenter. Any suggestion on physical topology and achieve failover configuration for internet please? Thank You,

This would the be essentially the same as integrating MPLS:

The documentation shows a topology example.

From what I can see, if you plug your direct internet link into WAN1 and your link to your DataCenter (with Internet breakout) into WAN2, it will just work as you want it to, assuming you retain the default settings - WAN1 is primary.    You have to ensure that both links provide Internet access to the Meraki cloud resources shown under ? ? Firewall info   - plus the WAN uplink test resources detailed here:  https://documentation.meraki.com/MX/Firewall_and_Traffic_Shaping/Connection_Monitoring_for_WAN_Failo...

Thank you both  Mloraditch and Greenman fore your inputs.

@GreenMan  the datacenter connection is L2 fiber connection so it doesn't have any kind of IP assigned. How can I make it work in this situation? Thank you
