can't ping tunnel interface !

Is it possible that there is an access list applied in the tunnel that might be blocking the ping? Is it possible that there is some mismatch in addressing within the tunnel? If you would post the tunnel configuration and the output of show interface then  perhaps we might be better able to find the issue.

Thank you for posting the configuration of the tunnel which is quite helpful. I suggest that you add this to your tunnel configuration and see if it works better:

ip nhrp map 172.88.0.228 172.10.47.10
