11.Click the Task button. When investigating tunneling, you decide to use snoop to examine the way header and encapsulation works. You ping the destination address of the tunnel and get a successful reply. In the snoop output you discover these protocols: ICMPv6 ETHER IPv6 IPv4 Place the protocol types in the order of encapsulation in which they would be observed in the snoop output. Note: Box 1 should contain the outermost protocol in terms of encapsulation, and Box 4 should contain the innermost encapsulated protocol.
