3-stage clos

[Karthik Balaji G]

Hi,

First off, great initiative! I am trying to evaluate OpenClos for our DC network. We have a three stage clos network - TOR, Leaf and Spine . All of those layers, up to the servers are running eBGP.

I looked at the code. Looks like OpenClos already supports config generation for leaf and spine switches. How difficult would it be extend OpenClos to support automated configuration generation and ZTP of all three layers?

Thanks,
Karthik

Hi Karthik,

3-Stage comprises of Spine and Leaf. Leaves are TOR.

5-Stage comprises of Fabric, Spine and Leaf. Again Leaves are TOR.

OpenClos has 3-Stage implemented with ZTP for complete out of box automation. The work for 5-Stage is still in progress. You can use following file to automate ZTP.
