hi
During plug and play and onboarding does DNAC configure these extended nodes with LISP for example or do they act like a trunked switch only with the uplinks carrying the Vlans only?
as far as i understand it from manuals EFN works as NEAT switch. no LISP there
Is the only configured L3 interface the one within the Infra_VN for communication to shared services?
yes
Does it use the uplinked edge node as the GW for the networks?
yes . in infra_vn
I'm assuming I could connect standard end hosts to the extended nodes If required and not just IOT / APs?
of course
