Possible to have weighted default route for a certain subnet? 3750x

Looking for help with a certain issue...

 

We have 2 circuits into our location, 1 for data side and 1 for VoIP.

 

Currently - the data side is used a failover for the VoIP but we need to manually fail them over when the MPLS goes down.

 

Is it possible to setup weighted default routes on the switch without using BGP?

It's definitely possible using Enhanced Object Tracking. Are you redistributing routes from your MPLS router using an IGP? If so, you can track the presence of the route and have your default route point in one direction if the tracked route is present and another if it isn't. If you're not redistributing routes to the switch, you can still do this using an IP SLA process. Can you provide more details on how your switch is currently handling routing?

Thank you very much for the response!

 

This particular switch only has a few static routes.  We are not redistributing routes through any dynamic protocol.    

 

It looks like IP SLA's are what I need to look at.
