Been a while since I've done this so just need a quick refresher
Currently building our DR site with the intension that our pool of WAN IPs will be able to failover from Site A to Site B.
Both sites have ISR routers and /30 fixed subnets as the point to point between us and the ISP.
Our pool of production IPs is a /24 that's currently statically routed to Site A by the ISP.
Plan is to enable BGP at Site A + Site B and inject that /24 route ourselves.
That much I can handle, but remind me how I set the metric so that Site A is the Primary and Site B is the secondary?
Site A goes offline, ISP updates it's routing tables automatically and sends traffic for that subnet to Site B instead.
