Hi Acee, Ketan and Aijun, I also agree that the introduction of source router ID could be a generic useful extension to OSPF, we already have this in IS-IS [RFC 7794]. As for the inter-area topology retrieval use case, I tend to agree that there can be multiple ways to achieve this, thus it w

Hi, Rob: If we use BGP-LS to get the underlay topology, we will not consider deployment other methods such as IGP adjacency or LSDB telemetry, although all of them are applicable. If we deploy BGP-LS adjacency with routers in multi-area to get the full multi-area topology, it will be no dif

Hi Acee, According to our logs, although we made individual registrations through the early allocation process, it looks like all of the RFC 7684 registries at https://www.iana.org/assignments/ospfv2-parameters were created in September 2015, after the document was approved by the IESG. Amand

Hi Amanda, It seems to me that we created the RFC 7684 TLV registry via early allocation so that we could allocate code points from other drafts. If this is, in fact, the case, we'll need to manage the IGP MSD Type in the WG. Thanks, Acee On 7/24/18, 4:25 PM, "Amanda Baber via RT" wrote:
