Is there any particular benefits of integrating Meraki networks with a Viptela network over other SD-WAN solutions since both are CISCO solutions? In terms of deployment, maintenance, visibility, security etc.
I don't see why you would do this. You would choose one and stick with it.
For example using Viptela for the backbone (between DCs or larger sites) and Meraki for smaller regional networks to reduce cost.
You lose so much of the SD-WAN capabilities by mixing them - I just wouldn't do it.
@Khoa : I am using Viptela for all my large branches but for remote locations i am using Site2Site VPN with Meraki for some locations. @PhilipDAth is correct, for SDWAN i would recommend to go with one of it.
@Inderdeep: for the setup you have made, which I believe is the non-meraki site2site vpn, all ipsec details will be coming from the Viptela side and that would limit the IPs that the Meraki can learned from the Viptela routes. Will you be able to share the setup or diagram?
It completely depends on your requirements.
Meraki is a fantastic solution if all the requirements can be met with it. Don't overcomplicate things by adding a separate technology and management/control plane into the Mix.
That being said you could have a Meraki and Viptela solution working side by side.
The only main reason I'd see you looking at a Viptela solution over Meraki is for some advanced SDWAN steering capabilities and layer 3 segregation (VRF) for compliance reasons.
