Best Practices for Configuring VLANs Between Trunk in DNA Center, SD-W

[banoosh]

Hello everyone,

I am currently working on a network design involving Cisco DNA Center and SD-WAN routers. I am looking for best practices to configure VLANs between trunk ports connecting DNA Center-managed switches and SD-WAN routers, as well as access port VLANs for end devices.

Specifically, I need guidance on the following:

1. VLAN Trunking: How should I properly configure VLANs between the switch and the SD-WAN router over a trunk port? Are there any specific configurations to be aware of when managing VLANs from DNA Center or switch level?
2. Access Ports: What are the recommended configurations for access ports that belong to specific VLANs? Should these VLANs be statically defined on the SD-WAN router or handled differently?
3. Management VLAN: What are the steps to set up a management VLAN in this context, and are there any specific considerations when integrating it with DNA Center and SD-WAN?
4. Static Routes: How can I efficiently configure static routes to ensure proper routing between VLANs and external networks, especially when the SD-WAN router is involved?

Any examples, step-by-step instructions, or considerations for VLAN best practices and static routing in such a setup would be greatly appreciated. If there are any configuration templates or design guidelines from Cisco’s recommendations, that would be helpful as well.

There is integration document shared here :

https://www.cisco.com/c/dam/en/us/td/docs/solutions/CVD/Campus/Cisco-SD-Access-SD-WAN-Integrated-Domain-Guide.pdf

Which explain how you can integrate SD-WAN network (that is behind SD-WAN network Switches to be part of SD-Access)

there are different method of transits, but you need to consider here is ip transit.

Note : i would advice to engage with Cisco integrator to help, there are lot of areas required lot of changes to integration to work as expected.
