My company has a re-design of our campus network coming up. I have been taksed with implementing a switch stack in a new building being added into the campus network. There will be 3 buildings in a ring topology each running a layer 3 switch stack using eBGP to transfer routes between each building with dark fiber connecting them. Our principal network engineer as instructed me to spread the switch stack into 3 racks using a ring design for stacking (see attached picture). All 6 switches in the stack need to have the exact same stack priority number as seen in the diagram (high lighted in yellow), and they should each remain the same switch priority number even if they all loose power and boot up out of order/sequence. Can someone tell me how to ensure that the switch stacking priority displayed in the diagram always come up this way even after power loss and out of sequence switch boot ups? Are there commands I need to use to assign each switch a static priority number? Are there any considerations that I'm not thinking about that should cause me to avoid setting static switch stack priorities in each member of the stack? The ring stack design is not supposed to change so anyone that can offer advice please keep in context of my question. Thanks!
