SD-Access Intermediate Node

[henockk]

Hi All

I was going through Cisco SD-Access and I wonder weather we must acquire Intermediate node or our core switch i.e catalyst 9500 can act as Intermediate node. Thanks for your answer.

Hi henockk, 

as a distribution switch is optional so is a Intermediate Node. As the design guide describes it is only there to bring IP reachability in the underlay between (mainly) Border and Edge Nodes: https://www.cisco.com/c/en/us/td/docs/solutions/CVD/Campus/cisco-sda-design-guide.html#IntermediateNode

You can also have a look at "Very Small Site" or "Small Site" Design in the linked Guide. BRKCRS-2502 gives a nice overview too.
