Aviatrix and Meraki SD-WAN Integration Step by Step!

Hello All,

I saw this video and a had a doubt about necessity of landing transit that connect VPC of Meraki. Can do directly from VPC Meraki to TGW?

Another doubt based mention of new Meraki to receive routes from HUB, because in the topology mention about " another org ", so is it related with another organization in Meraki Dashboard?
