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.
