Dynamically choose fastest route

Brian Green · ‎08-26-2015

I have a question - can I dynamically assign the route metric to a static route?

Background: I have a Hub-and-Spoke setup that uses DMVPN to create the tunnels. It is possible that the spokes talk to two (or more) different hubs. The spokes have a link between them. What I would like to do is, if the connection between Hub1 and Spoke1 uses a slow connection (i.e. satellite) and the connection between Hub2 and Spoke2 uses a fast one (for example, the Internet) send traffic from behind Spoke1 across the link to Spoke2 and into the tunnel there. But this would need to be dynamic to a degree as I can't say what carrier(s) the end-user will be using before they depart.

Unfortunately the configs are not local to this network, so I'd have to retype and sanitize them to put them here.

Thanks for any thoughts or ideas!
