Most people run dual DMVPN clouds with two tunnels on the spoke.

One primary cloud for CM and one for the T1 side.

Your failover comes from the dyanmic routing protocol running over the clouds (ie: eigrp).

On the spoke you put a /32 route for the two hub ip's out each respective internet link.

All,

I have a site that has a cable modem and a T1.  I was able to
configure internet access redundancy using IP SLA/track.  This site is
also spoke side of a DMVPN mesh.  Is there anyway I can make DMVPN to
failover to the other connection?  I can't find any reference to it so
far.  I am not sure what you can do when the tunnel interface for
DMVPN you have to specify "tunnel source" and that will be different
depending on which link is up and running.

Thanks,
