Alternate Routing Question for MPLS network
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.

A simple solution would be to place a static route in the router with a high cost. Once the primary drops the higher cost route will then be used and then when the primary comes back up it will have a lower cost and take back over.

So, are you saying that on the Hosting1 router, where I have a summary defined in BGP, I should create a route to 10.19.24.0 via 10.19.24.1 weight [30] so it would be higher then eBGP[20] and have the static router redistributed to the rest of the routers in my MPLS network?

Those were exactly my plans, but am looking for other options, or to make sure that I am chosing the best methodology for this plan. I will keep this open for 7 more days and if no other responses, will award points as promised.
