DMVPN with EIGRP Named

I created a base DMVPN lab with 17 routers so that I could play with different routing protocols running across a DMVPN.  The first protocol was a basic EIGRP named configuration.  Nothing much to it.  Made sure that split horizon was off. as well as turning off next hop self on the hub.  Had full layer three reachability.  Even went in and played with a couple of options in EIGRP since I have only done named mode once before.  Not that bad.

Here is the config that I made for the EIGRP section of the hub.

router eigrp INTERNAL
 !
 address-family ipv4 unicast autonomous-system 100
  !
  af-interface default
   authentication mode md5
   authentication key-chain EIGRP
   passive-interface
  exit-af-interface
  !
  af-interface GigabitEthernet1/0
   no passive-interface
  exit-af-interface

  af-interface Tunnel0
   summary-address 192.168.8.0 255.255.248.0
   summary-address 192.168.16.0 255.255.248.0
   no next-hop-self
   no passive-interface
   no split-horizon
  exit-af-interface
  !
  topology base
  exit-af-topology
  network 3.3.3.3 0.0.0.0
  network 192.168.0.3 0.0.0.0
  network 192.168.23.3 0.0.0.0
  eigrp router-id 3.3.3.3
 exit-address-family
!

There weren't any real gotchas on this one.  Pretty straight forward.

Here is a pic of the lab that I made as well.
