Abstract:
   BIER is a scalable multicast overlay [RFC8279] that utilizes a
   routing underlay, e.g., IP, to build up its Bit Index Forwarding
   Tables (BIFTs).  This document proposes Fast Reroute for BIER (BIER-
   FRR).  It protects BIER traffic after detecting the failure of a link
   or node in the core of a BIER domain until affected BIFT entries are
   recomputed after reconvergence of the routing underlay.  BIER-FRR is
   applied locally at the point of local repair (PLR) and does not
   introduce any per-flow state.  The document specifies nomenclature
   for BIER-FRR and gives examples for its integration in BIER
   forwarding.  Furthermore, it presents operation modes for BIER-FRR.
   Link and node protection may be chosen as protection level.
   Moreover, the backup strategies tunnel-based BIER-FRR and LFA-based
   BIER-FRR are defined and compared.
