Questions about BGP in the Data Center (with a Whiff of SRv6)

Henk Smit left numerous questions in a comment referring to the Rethinking BGP in the Data Center presentation by Russ White:

In Russ White’s presentation, he listed a few requirements to compare BGP, IS-IS and OSPF. Prefix distribution, filtering, TE, tagging, vendor-support, autoconfig and topology visibility. The one thing I was missing was: scalability.

I noticed the same thing. We kept hearing how BGP scales better than link-state protocols (no doubt about that) and how you couldn’t possibly build a large data center fabric with a link-state protocol… and yet this aspect wasn’t even mentioned.
