I need to implement EEB on my branch networks which are all connected with DMVPN, know the spokes are configured with Static routes towards the ISP but i need to enforce an IGP or EGP so i can use EEM to let me know when the connection to the ISP has fallen. EEM must be used for tracking of primary link, because the secondary is LTE /(Lets just say if the primary fails the secondary is very expensive) :)
What is good practice?
Can EBGP be implemented with the ISP for all of the spokes, this will lead to more than one network with the same AS?
Or is DMVPN with Eigrp the best solution, with eem tracking Adj with the Hub?
