Redundant Core Switch

Clients: I have redundant “core” switches with single controllers, with 4 additional switches connected to each “core” switch. If I loose a “core” switch, then about half a floor would

Question About Core Redundancy Best Practice : r/networking

ECMP just lets the access-layer switch understand that either of the redundant uplinks is a valid path towards the rest of the routing table. So unlike STP, which would want to cutoff one uplink, you can

Redundancy for Core Switch Stack : r/networking

So when one of the "new core" switches goes down, anything connected to it will still be offline. You can design around this by having redundant connections to the different "cores" and
