We need to write a DR plan and we only have one single ER circuit.
My question is: can we create another ER Gw (with the same settings as the first one) in the paired region (if the whole main region goes down) to access the onprem resources? I would like to know if there is a possibility of tapping into the same ER circuit from other (paired) region. My thoughts are that the azure end of the ER terminates somewhere at the edge routers that are shared between regions but I could not find anywhere on the MS docs.
I know there are possibilities to achieve this with multiple ER circuits or even with a VPN gateway in the second region.
