Currently, we have three main sites that I would like to discuss. We have our main HQ and two other sites. The site labels Hosting1 is where our production servers are and the one labeled Dev/QA/DR is just as it is labeled. Currently, I advertise BGP routes for connected networks for all three sites (the subnets are on the image). What I would like to do is have a backup route to advterise the Hosting1 nework subnet to the DR/Dev/QA site if the Hosting1 circuit goes down. I know I can do this manually, but would like something dynamic in case this happens at 2am. Also, I will need the backup route removed and the preferred router readvertised when the circuit comes back up. I have some ideas, but wanted to ping this off of everyone here. Thanks in advance for everyones' contributions.
