Problem with that is that this command only appears at 12.3(2), and not with
12.2(15)Tx.......
As far as I have checked already, DMVPN is not behaving completely to
"marketing specs" at 12.2(15)T, and you'll need at least the "spoke-to-spoke
functionality" IOS (which is more a bug fix than a feature IMHO) to make it
work accordingly.
Problem is that the Cisco CCIE lab uses 12.2T according to their blueprint,
so DMVPN will have it caveats in getting it to work.
Just a crazy idea: maybe by disabling route-cache on the spoke routers the
next-hop will still be "seen" as the hub address, but the underlying logic
sends packets directly to the other spoke router ? Maybe you can try to find
out what *really* happens to the packets ?
Kind regards,
Koen.

Hi ,
You will need the no ip next-hop-self eigrp <as> command on the hub router
to have the next hop be the orginal next hop.

Emne: DMVPN and EIGRP
Hello all,
I have configured a basic DMVPN set up and running
EIGRP over the tunnel interfaces.
At the spoke routers, I see that the next-hop to reach
the networks beyond the other spoke points to the hub
router's tunnel interface. If I want to have
spoke-to-spoke tunnels, then I need to have these
next-hops point to the remote spoke routers' tunnel
interfaces.
According to the below document, to achieve this, I
need to use process switching on the tunnel
interfaces. (I am running 12.2(15)T)
http://www.cisco.com/warp/public/105/dmvpn.html#eigrp
I configured "no ip route-cache" on the tunnel
interfaces of the spokes to have it process switched.
But still I see that the spokes point to the hub
router's tunnel interface to reach the networks beyond
other spokes.
The other option is to run a different protocol, which
I am anyway going to try, but wanted to make this work
before I try that.
Anybody know how to make this work using EIGRP?
I have turned off the split-horizon at the hub
router's mGRE interface.
Thanks in advance,
Mohan
