Hi all,

one of the advantages of LFA-based bier-frr is that duplicates may be
avoided. However, I think this is only true if we have either

1) failure-spedific bifts (which is not preferred?)


2) the possibility to first process BFERs which are affected by a failure

If assumption 2) is acceptable, I think a single-bift draft for all
bier-frr solution is feasible.
