MPLS over FR.

  • From: Binita Jha <BinitaJ@netbrahma.com>

I have a doubt regarding MPLS over FR.
1) RFC 3034 says that the top label (DLCI) carries implicitly information
about the network protocol type. but how does it indicate about if the shim
header is present or not?

2) Also if the shim header is present then how do we know abt what network
protocol is present?

Kindly send me the answer if anyone has.
