Hi Gunter,

I just wanted to let you know that the expert has approved the assignment of the values listed below. We're in the midst of extensive updates to https://www.iana.org/assignments/bgp-ls-parameters for the recently-approved draft-ietf-idr-rfc7752bis-16, so we might not get them online till later tomorrow. They'll be posted at the same time as the 7752bis updates.

I should also note that 7752bis is changing the name of the BGP-LS Node Descriptor, Link Descriptor, Prefix Descriptor, and Attribute TLVs registry to "BGP-LS NLRI and Attribute TLVs" (per https://datatracker.ietf.org/doc/html/draft-ietf-idr-rfc7752bis-16#section-7.1.7). This should, I hope, be reflected on the website tomorrow. I'll let you know when everything's up.

thanks,
Amanda
