Re: BFD vs network brownouts

Thanks for the feedback, Jason, Saku, Tore, Tom, and Alex. Agreed that trying to effectively brute force (mis)use of BFD as I described is misdirected. To some degree I'm trying to reinforce a "why this doesn't work" argument internally as part of a larger narrative. Thanks specifically to Ja

I second the method Jared is suggesting, go hop-by-hop, check light levels, and make use of loopback modes to establish which partial sections may be working already. (If any loopback is available, I don't know your platform specifically) On 08.01.2025 22:19, Jared Mauch wrote: make s

Re: BFD vs network brownouts

BFD is binary. Service OAM 802.3ag / ITU-T Y.1731 generates time series data that talks to service reliability and SLA. OAM offers interface shut and fault propagation as well, which means it's both an observability tool and an operational one. BFD is just not the thing for measuring the reliabilit
