One of the joys of RIPv2 in a DMVPN network is Split-Horizon.  Just a quick refersher on Split Horizon – it is the rule that prohibits a router from advertising a route through an interface that the router itself uses to reach the destination.   This is done in order to prevent loops in the network, but with DMVPN we need to disable this feature via the no split-horizon command. Quick note:  When I am posting the configurations for the sites I will only notate the routing protocol additions.  If you need information on DMVPN configuration, see my previous post.
