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.

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
