encapsulation generally signifies the below in terms of OSI model as described clearly here
"Each “function” (broadly speaking) encapsulates the layer(s) above it. The network layer encapsulates the layers above it. The data link layer encapsulates the network layer, and so on."
Q:But many a times, we also see that terms like mac in ip encapsulation (e.g OTV).In this case, the upper layer(Layer3) is encapsulating the lower layer(Layer2). Please explain why do we use the term
encapsulation here. Is it not contradictory to what
encapsulation generally means?
