MPLS header and acronyms (CE, PE, P, Label Push, Label Swap, Label Pop)

[@shilpahv1993]

Thanks for great explanation! If P router is connected to another P router, you mentioned that label pop occurs. But in the first P router, Label pop happens and label is removed. Correct? Now, if it is connected to another P router and traffic is moved to P router, how does label pop occur?

label is just label :)

Can a PE router also act as P router ?

Is label Pop by P ?, Isn't by PE2?
