Hi all, in particular authors of draft-chen-bier-frr, in the introduction of your draft you state issues with tunnel-based frr, but the text is unclear to me: https://tools.ietf.org/html/draft-chen-bier-frr-02#section-1 To avoid this supposed shortcoming, you propose a different bier-frr approach. Can you clarify, please? An in-depts comparison between tunnel-based frr, which leverages frr of the underlay, and "native frr on the bier layer" can be found here: https://atlas.informatik.uni-tuebingen.de/~menth/papers/Menth20c.pdf The latter approach has been first published as [3] I. Wijnands, G. J. Shepherd, C. J. Martin, and R. Asati, Per-Prefix LFA FRR with Bit Indexed Explicit Replication, https://patents.google.com/patent/US20180278470A1/en, Sep.2018. AFAIK this is also the concept followed by draft-chen-bier-frr, but I am not fully sure as this has not been cited. Reaction speeds of both mechanisms should be similar as they depend mainly on the time to notification about the failure. Experimental results for draft-merling-bier-frr are provided in the paper cited in my previous email. Kind regards Michael -- Prof. Dr. habil.
