Hi Zhou
Can you post the config of your router ?
Also can you include the output of show ip route taken out from your router ?

Hi Zhou
As i already mentioned would suggest to post out the full config of both the routers since both your loopbacks loopback 1& 2 are showing as directly connected and you are using them as source and destination address of your tunnel.
Tunnel destination should be the remote end routers loopback address and you should have reachability to the same..
