For the last couple of years I have worked extensively with #SDWAN. Let me share with you some of the common design mistakes that I see, often to save a few bucks, which ends up costing more in the end. Let's focus on the transports. A 🧵
Don't cheap out on bandwidth. Bandwidth is relatively
cheap. Get two INET transports, from different
providers if possible. Have them be the same BW
and use them equally. Having them different BW
will complicate the design and policy.

For dual router sites, connect both routers to
both of the transports. This allows for faster
convergence and no need to configure TLOC
extension. ISP needs to provide two ports,
though.

There are not many pictures of me when everything started, I was always tinkering with computers. Sadly, those times were not picture-heavy of even as media-prone as now.
A friend took that picture, I was taking apart components from a motherboard, and she took it from behind.

How did it start? I was the typical IT geek touching and breaking things. I broke and repaired my own computer more times than I could count, and every time I was learning something new. Some I should *not* do😅
I enjoyed doing this and did it for free for my friends.

Here is a post where I will aggregate all the guides I used to setup my SD-WAN lab.
I used Google Cloud to host the SD-WAN lab. It consumes a lot of resources for a few WAN edges. I recommend setting up a GCP VM with 12 cores/24GB minimum.

I used the EVE-NG Pro cookbook to set up the lab.
eve-ng.net/index.php/docu… pages 41-50.
Once I set up the VM, I uploaded all the images to the GCP instance.
I then used this guide to get all the controllers up and runnning: pocvlab.com/cisco-sd-wan-c…
