Now that OSPF is all fixed I can set up the Dual-Hub DMVPN. I need to decide on an addressing scheme to go across the DMVPN network, and I think that 192.168.1.0/24 is suitable; it's far enough away from the main networks 10.1.x.0/24 subnets to be easily distinguishable.
There are a couple of things to remember here. Firstly, we need to open up the transparent ASA to permit the DMVPN traffic, and similarly on the failover ASAs. The DMVPN hubs also need to be NAT-aware, as we will connect the clients to the NAT address (10.1.16.200 and 10.1.26.200), rather than the loopbacks. Thankfully, they handle this part themselves, but we do need to factor this in (as you'll see later).
We will start off by creating the isakmp policy and transport-sets that we will use. Because it is identical we can create it on notepad, nd then paste onto the routers, or create it on one router and then do "sh run | s crypto" and then copy and paste:
Now we can start creating the tunnels, and it's easier to break out Notepad, and chuck in the basics:

Now we can start creating the tunnels, and it's easier to break out Notepad, and chuck in the basics:
