Dear Expert , I have DC and DR MX deploy as VPN concentrator HUB 1 and HUB 2. we have branches at MX 68. HUB1 at DC is the primary , DR is the secondary HUB , so any traffic MX68 at branches would forward to HUB1. i have test when we shutdown HUB1 at DC , MX68 at branches's route will change default route to HUB2 at DR. my question is that , what if connection ISP VPLS at DC down , MX at branch can't reach to DC MX HUB , but DC MX HUB still up and can access to internet as normal , in this case , Meraki MX at branches would change route to DR or not ? and if yes , how long that it will change the route ?
