Hi Albert,
Thanks for your feedback from an operator perspective – it is valuable. This
“BFD hold up” behaviour that you desire is best handled by BFD since I would
expect that similar behaviour would be desired across routing protocols (OSPF,
ISIS, BGP) and perhaps other clients.
IMHO this is
Sue,
I support progress of this draft, it addresses real problem.
On Redback side of things we have implemented this around 2013, logic
(proprietary) kept in BFD indeed, so +1 Ketan. I’d document it as an informal
feature, that is recommended (same for YANG)
Cheers,

Hi Ketan,
I think it will be good to mention this in the doc, as I expect most large
networks concerned with network stability impacted by link flaps to enable
the BFD hold-up feature.
For example, if one side has BFD hold-up enabled (> BGP hold time) and the
other side does not, the BGP keepaliv
Hi Albert, Ketan,
The authors will document dampening in the operational considerations. I’m also
of the mind that the dampening should be done in BFD rather than the BFD
clients (e.g., BGP).
Thanks,

Hi Albert,
Thanks for the support and valuable comments from a customer’s perspective.
This BFD ‘hold-up’ request actually applies to all BFD clients (e.g. control
protocols).
I think that BFD would be a better component to apple this BFD hold-up as Ketan
also mentioned.
However, some specifica
Hi Acee,
I imagine that there could be multiple clients of the same BFD session with
different requirements in regard to dampening behavior. For example, the
delay each client desires to use may be different for each client of the
BFD session. If that is a plausible use case, I think that placing

We’ll take your opinion under consideration.
