Section 6 says: 

   When BFR2 receives the route, it calculates its BIFT entries.
   Because the route from BFER1 does not include a BIER Nexthop, BFR2
   uses BFR1's BFR-prefix as the next hop.

It should say:

   When BFR2 receives the route, it calculates its BIFT entries.
   Because the route from BFER1 does not include a BIER Nexthop, BFR2
   uses BFER1's BFR-prefix as the next hop.

Notes:

The original text mistakenly says "BFR1's BFR-prefix". Given that the route is explicitly stated to be "from BFER1", the next hop should logically be "BFER1's BFR-prefix". This correction ensures consistency and technical accuracy in describing how BFR2 determines the next hop.
