Good evening Ronnie / Anthony,
Just started this course and i have a quick question. With regards to the 2 tier Spine and Leaf configuration, is there a Cisco recommended limit to how many nodes you can have at each layer?

Thanks,
Cecil

@Cecil-Burrowes,

There is no upper limit here but the physical hardware (i.e. number of ports). As long as you can have a full mesh between spine and leaf nodes, you can keep adding...of course each leaf node would need to use a certain number of ports for actual devices.

The minimum would be for at the least for redundancy, fault tolerance and high available. So you could not have a Single Leaf to a Single Spine node.
