Pieter, I would agree that these are required for certain DMVPN scenarios, but not necessarily important in Simons case. These settings are only required in DMVPN if you wish to allow direct spoke to spoke tunnels, i.e. to prevent spoke to hub to spoke traffic. If the task or scenario does not require spoke to spoke tunnels then these settings are not required in the configuration. Simon, you may need to adjust your eigrp timers if your DMVPN runs across some poor performance wan links for instance ( we have had to do just this in a production DMVPN environment ), but if this is a lab scenario then I would be surprised.
Are you doing this in dynamips perhaps?
