IP Address on Physical vs Bridge Interface

RouterOS General
1

It appears if you take the route of placing your WAN/Upstream service IP address on a bridge interface and the upstream ISP device loses power, the router does not register the service as down.

This being said, is it better to place your WAN/Upstream service IP address on an Ethernet interface directly?

My fear is that if I have a primary and backup route in place (i.e. two ISPs) the address on a bridge interface the backup route will never kick in.

I could be overthinking… thoughts?

I would put the WAN address on the physical link. I cannot think of a reason where the WAN IP would be beneficial on a bridge interface.

On e benefit would be portability with respect to the configuration.
