Luis,


If router A pings router B for addresses routed through th tunnel. The IP packet will be encapsulated with a GRE Header , this header is only deencapsulated at the GRE tunnel end to reach its deired destination.



So, No matter what do you have between 2 GRE tunnels in between, the packet traversing the tunnel is not revealed because its encapsulated while the packet is forwarded to the destination.



Hope this helps, Let me know if this addressed you enquiry,



Mohamed
