Per il querier: un router allo startup parte come querier, se riceve una query da un router con IP piu' basso, diventa non querier. In poche parole il querier e' il router con l'IP minore.

La quick awareness significa che allo startup, il router querier manda delle membership query a distanza molto ravvicinata in modo da avere il piu' velocemente possibile informazioni relative alla membership gruppi multicast sulle sue attached networks: in pratica, all'avvio la prima cosa che il router deve fare e' sapere se ha dei membri di quei gruppi nelle sue reti oppure no per sapere cosa e come forwardare, e in quetso modo ottiene velocemente le info che gli servono.
