I did. You don’t remember it. It was that memorable. >> Because the thought of trying to deploy this capability at scale without >> this attribute seems impossible.

There is no management plane. We had the chance at one, but we had the great schism between OpenConfig and the IETF. So now we have nothing that we can rely on. > How did those providers make changes to their configs/features/architecture > before? > I would expect them to use the same tools. They have configuration databases, but they do NOT have good tools that tell them about router capabilities. They MAY be able to do something ad hoc based on software release numbers, but this is far from a good solution. >> And the routers will do computations based on the multi-part TLVs. >> One level of indirection for a capability does not seem extreme. > > Not extreme, indeed. > But again, I rather not see 20 different minor or irrelevant things > in the router-capability TLV.

This was outside of IS-IS entirely. Several people disliked it so much that they wanted it thrown out of the WG.
