Hi Ketan,

Thanks for the quick response, so for clarity, does this mean that a device that implements that RFC would always be expected to unconditionally advertise the S-BFD Discriminators TLV via BGP LS if BFD is configured?  I.e., there would be no reason to control whether or not this information is sent.

Thanks,
Rob

Subject: Re: Robert Wilton's No Objection on draft-ietf-idr-bgp-ls-sbfd-extensions-09: (with COMMENT)

Hi Rob,

The extensions in this document do not introduce any config-related change to the BGP model.

However, at some point, the WG would need to work on a BGP-LS operational model that can be used to report the state advertised via the protocol. This draft would be adding a TLV to that operational BGP-LS state. I am not aware of a draft as yet, but this has come up in private discussions with some WG members.

Thanks,
Ketan

COMMENT:

Hi,

My only comment doesn't directly relate to the content in the document, but I
would like to check whether any new YANG data nodes are required to configure,
enable, or manage this extension and if so that they are being tracked by the
WG chairs, or via another document so that they don't get forgotten.

And a +1 on 6 authors on a 7 page document seeming excessive.

Regards,
Rob
