Activating BGP to peer with a third party data centre
We're getting closer to what I hope will be a relatively simple task but I'm way out of my depth here so thought I would ask if the community has any advice on the subject.
Essentially, we have an existing SD-WAN covering around 30 sites in Europe. The rest of our global organisation are using other technologies for regional connectivity and our top level idea is we deploy one (probably an HS pair) of our Meraki organisation MX's into each of the other regions, and have them peer locally using BGP to share routing between their local region and our MX so we have dynamic routing across the regions.
The Meraki documentation is reasonably good but I've logged a support ticket to ask a few extra questions, mainly around timescales for activation and what interruption (if any) we are likely to see to our existing SD-WAN when we ask the support team to activate BGP.
Does anyone have any experience of setting up BGP and if so any pitfalls we should look out for?
