How to config backup route in MX 450?

[MicJameson2]

Hello.

I am using hardware MX 450, with OS version 18.211.2

This device is connected to Azure with two "Azure expressway" links. The client wants a third backup VPN link.

In short, I'd like to, at least logically, apply the same backup route config as I do in standard Cisco switches which is a floating route:

I simply add a second route to the same location, but apply a higher administrative distance than the existing primary BGP route, so if my BGP connection fails, and thus removes the BGP route from the routing table, the floating route will promote to the production route.

---

Seemingly and after research, I cannot manipulate the administrative distance in MX switches. Google info states that to accomplish my task I could try manipulating keepalive and/or timeout sensors, but I do not see these sensors in the MX GUI.

Can you please tell me how to accomplish my stated goal?

Thank you!

Where are these routes pointing to, are this autovpn learned routes or lan routes? 

Meraki doesnt really have such thing. But maybe you can set some static supernet route that covers some bgp subnets.

It's probably best to think of the MX as an SD-WAN appliance rather than a router per se.    It's designed to make adopting SD-WAN loads simpler, for the majority of customers who often have broadly overlapping requirements - it's deliberately designed to avoid a million tunable settings, that most never use and generally just make the whole thing complicated.

I think we'd need to have more information around your overall setup and requirements to advise further.   You may be best reaching out to your meraki account team and/or a Cisco partner to discuss in depth..?
