Assuming that the VIP is part of a /24 or larger which you have
permission to route, it should be fairly simple to just announce it to
your provider via BGP.

You may need to create an aggregate or generated route for the network
that the VIP is a pert of and then use policy to announce that via
BGP.

If you provide a bit more detail on your topology I am sure I or
someone else here could give you a pretty good config example...
