One difference from the real internet: since traffic volume is relatively small and no money is exchanged, there's not really a distinction between transit and peering - you could do peering-only if you wanted to, but mostly everyone provides transit to all their peers, making the network a completely unstructured mesh (other than the large number of stub ASes who never bothered to get more than one peer!)
off topic: i always thought mini internets like dn42 would be a super cool place to run secret/private services. fun to imagine.
