Hi,

   1. Re: New Version Notification for
      draft-ietf-bfd-stability-07.txt (Reshad Rahman)

This feature  is good to have. As a matter of fact, we have been trying to get vendors to expose BFD counters as we know links from carriers do drop packets without any indication of errors, and the basic send/receive counters are not reliable indicators, since the timers are randomized up to 25% lower.

The draft talks about geneation of diagnostic info but no details. I would think syslog is not practical for large network. What do you think about mentioning keeping counters of missing seq numbers, and have these counters exposed to telemetry/snmp? This would be very useful to us.

Thanks

Albert
