1. Is label stacking means pushing the whole 32 bits header of MPLS for
each label , or only the 20 bits label field?
2.Regarding Route Distinguisher - How does RD converted to a single
label (RD is 26 bits while MPLS label is only 20 bits)?
thanks ,
3.why does lookup process in a regular (IP) router takes longer time
then in ab MPLS Router ?
4. Is it possible to use IPsec (Transport or Tunnel mode) over MPLS
Core Network?
5.Is possible to run (encapsulate) an ATM packet over MPLS/IP Network?
