Does Windows have a check gateway feature?

Question

Network administration

Good afternoon, comrades.
My question is simple, but Google could not answer me.
I have two routers R1 and R2 wrapped with ospf between them.
There are many small networks cut into VLANs.
Each of these routers publish default gateway
I need to somehow reserve gateways on window servers.

• The first option that came to mind is VRRP, on a test bench, and everything works well in a combat condition, but their number confuses me in the future, since in the future we are going to use q-in-q in the configuration.
  
• The second option is RIP, everything started up on the test bench, but again, the very fact of installing RRAS on windows confuses me for the sake of such a trifle as “access to one UDP port” (as an example).
  
• And the third option is to statically assign several gateways with different metrics (distance) on windows servers.
  
• OSPF variant, I do not consider it, since in windows 2008 its support was canceled.
  

I want to pay attention to the question only to Windows
Oh, yes, the question is this.
Poke your nose into the documentation by which algorithm the default route is selected, because if there is such an opportunity, how to specify a different metric (distance), then there is some algorithm in windows for checking the availability of the gateway (check gateway), what is it arp or icmp or what something else, that's exactly what I couldn't find.

Answer 1

You are confusing the concepts of Metric and Distance a little.
Consider an example if
1) there are the same directions with different gateways and different Distances - it will use them in order starting from the smallest to the largest (if unavailable with different verification methods)
2) there are the same directions with different gateways and different Metrics - the route will be used with the smallest metric, excluding routes with a higher one. Even if the gateway is not available.
PS: As far as I know, windows simply does not have the concept of Distance and the gateway control system
PS2: It is decided, as an option - either by its own implementation, or through a bunch of "scripts + console route", or by external programs
