802.1BR has been around for almost 10 years. I am curious if anyone is actually using it in the Campus? All the vendors have support for it, but with different focus. Cisco's focus as been on the DC on their Nexus switches. Juniper is flexible with Campus and DC. Extreme and Ruckus have seemed to have focused on the Campus.
The concept is interesting. I think I can understand the use case. Management of all edge switches from the campus core. But like all technologies, just because you can, doesn't meet you should because I see a lot of caveats. Looks like you deprecate stacking in the IDF, the switches are just cascading at 10GE. And from what I see most vendors recommend you keep the rings under 4-6 switches. And it looks like both Ruckus and Extreme have an upper limit of ~40 total PE's. list goes on and on.
So is anyone actually rolling it out as a campus edge at scale?
