BIER in non-MPLS netowrks
as decsribed in section 2.2 ihttps://tools.ietf.org/html/draft-ietf-bier-mpls-encapsulation-10 with BIFT encoding from: https://tools.ietf.org/html/draft-wijnandsxu-bier-non-mpls-bift-encoding-00 changes: 1 - introduce the new BIFT lookup table. BIER tables that have an associated MPLS label are added to the MPLS-FIB. Those that don't are added to the BIER table 2 - BIER routes that have no associated output MPLS label will add a BIFT label. 3 - The BIER FMask has a path-list as a member to resolve via any possible path.
