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:

Our topic today on Heavy Networking is SD-WAN monitoring at massive scale. Scale can grow quickly with SD-WAN when you account for the underlay, overlays, gateways, endpoints, and more. We talk with sponsor Broadcom about their monitoring platform and dig into a case study with a Broadcom customer providing global IT infrastructure for thousands of their own customers.
The post Heavy Networking 701: Monitoring SD-WAN At Scale With Broadcom (Sponsored) appeared first on Packet Pushers.
