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.
