Hopefully this is an easy one.
Can anyone explain to me why the documented formula for full mesh total tunnel count is ((H)*(H-1)/2) * L1 instead of ((H)*(H-1)/2) * L1 * L1 ?
Seems to be a simple geometry node formula and if each node has the same number of interfaces wouldn't there be a vpn tunnel per pair making the final factor squared?
The documented formula for the tunnel count per MX has this term squared, meaning there actually is a vpn tunnel per pair of interfaces, so why is it not squared in the total tunnel count?
Same thing for the Hub part of the total tunnel count of the Hub and Spoke topology. It should be identical to the full mesh total tunnel count, correct?
The documentation is here: Auto VPN Hub Deployment Recommendations - Cisco Meraki
I want to earn the Meraki cert, but I'm concerned about the exam questions requiring calculation on these formulas. Would the exam questions require correct calculations as documented, or as I suspect the correct formula should be?
