-**The configuration @ FreeBSD router:**
-ifconfig gif0 create
-ifconfig gif0 inet 10.100.100.2 10.100.100.1 netmask 255.255.255.252
-ifconfig gif0 tunnel 192.168.1.2 10.242.2.242
-**The configuration @ M7i:**
-<code>
-show interfaces ip-1/2/0
-  unit 0 {
-    tunnel {
-      source 10.242.2.242;
-      destination 192.168.1.2;
-      routing-instance {
-        destination VRF-TEST;
-      }
-    }
-    family inet {
-      address 10.100.100.1/30;
-    }
-  }
-</code>
-And also don't forget to define the ip-1/2/0.0 interface in the correct routing-instance (in this case, VRF-TEST routing -instance)
-Network topology for testing purpose is shown below:
-.100.100.2/30 (ipip tunnel) 10.100.100.1/30 FreeBSD ----------LAN------------M7i 192.168.1.2 10.242.2.242
-And finally, based on the result below, we could see that it is possible to do ipip/gre tunnelling in M7i base system without AS PIC or LS PIC. M7i base system has 1 builtin tunnel interface.

-And these are the results:
-I did ping from the M7i
-<code>
-# run ping 10.100.100.2 routing-instance VRF-TEST
-PING 10.100.100.2 (10.100.100.2): 56 data bytes

-and this is the result:
