SD-WAN Basics

[RS19]

Hi

Please help me in understanding the below points.

1) For a network setup for nearly 40 ~ 45 branches what is the recommended practice for placement of the below components.

  a) vBond - Cloud or On premises

  b) vManage - Cloud or On premises

  c) vSmart - Cloud or On premises

2) Configurations are prepared in vManage.

      - Configurations are pushed from vManage to vEdges directly : Is my understanding right ?

      - Do configurations are pushed from vManage -> vSmart -> vEdges ? : If this is also correct what configurations are pushed via vSmart to vEdges ?

Hi,

Controllers placement depends on many factors. For small deployment with 40-45 sites I would prefer cloud based solution for all controller elements if not additional constraints. 

You're right, configuration is pushed via control plane tunnels directly from vManage controller to Edge router. vSmart pushes policies (data, app-route, etc.), not configurations strictly speaking, you can see them via  show policy from-vsmart

Here you can find more info about SD-WAN/Viptela policies: https://sdwan-docs.cisco.com/Product_Documentation/Software_Features/Release_18.3/06Policy_Basics/01Policy_Overview/01Viptela_Policy_Framework_Basics

Thanks.

Understood that deploying in Cloud is recommended.

1 query regarding this. Is there any cloud solution from Cisco which we can use it like shared tenant model or we should deploy these by ourselves in cloud like Amazon or google ?

Regarding policies, is configurations like route leak are considered as policies which are configured from vSmart & pushed into Edge.

vManage supports multitenancy. You can also place your controllers in AWS or Azure and manage it yourselves certainly.

Cloud hosted controllers are spun up by Cisco for customers.

Route leaking is configurable through vManage policy. Here is more information:

Thanks for the below.

Cloud hosted controllers are spun up by Cisco for customers.

so this means vBond, vSmart & vManage will all be provided by Cisco & we will be using its service as a tenant.
