   (simplified) BIER-TE Bit Index Forwarding Tables (BIFTs):

   BFR1:   p1  -> forward_routed() to BFR3
           p2  -> forward_routed() to BFR4

   BFR3:   p3  -> local_decap()
           p5  -> forward_routed() to BFR6

   BFR4:   p4  -> local_decap()
           p6  -> forward_routed() to BFR6

   BFR6:   p7  -> forward_routed() to BFR3
           p8  -> forward_routed() to BFR4
           p9  -> local_decap()
