Johannes Resch submitted the following comment to the Is Dynamic MAC Learning Better Than EVPN? blog post:
I’ve also recently noticed some vendors claiming that dataplane MAC learning is so much better because it reduces the number of BGP updates in large scale SP EVPN deployments. Apparently, some of them are working on IETF drafts to bring dataplane MAC learning “back” to EVPN. Not sure if this is really a relevant point - we know that BGP scales nicely, and its relatively easy to deploy virtualized RR with sufficient VPU resources.
While he’s absolutely correct that BGP scales nicely, the questions to ask is “what is the optimal way to deliver a Carrier Ethernet service?”

I’ve just started a new series on network models over at Packet Pushers. The first two installments are here:
I’ve been writing a series about working within the IETF to publish a new standard over at Packet Pushers. The most recent installments are:
Here’s a preview of what I’m working on for those who are interested:
