Nangona zombini zisetyenziselwa ukutshintshwa kwenethiwekhi, kukho umahluko kumsebenzi.

Umahluko 1:Umthwalo kunye ne-subnetting ziyahluka. Kukho kuphela indlela enye phakathi kokutshintsha kwe-Ethernet, ukuze ulwazi lugxininiswe kwikhonkco enye yonxibelelwano kwaye ayinakwabiwa ngokuguquguqukayo ukulinganisa umthwalo. I-algorithm yeprotocol yomzila we-router inokukuphepha oku. I-algorithm yeprotocol ye-OSPF ayinakukwazi ukuvelisa iindlela ezininzi kuphela, kodwa iphinde ikhethe iindlela ezahlukeneyo ezifanelekileyo kwizicelo ezahlukeneyo zenethiwekhi. Ingabonwa ukuba umthwalo we-router mkhulu kakhulu kunolo lokutshintsha kwe-Ethernet. Izitshixo ze-Ethernet zinokubona kuphela iidilesi ze-MAC. Iidilesi ze-MAC ziidilesi zendawo kwaye zinesakhiwo sedilesi esicaba, ngoko ke i-subnetting ayinakusekwa kwiidilesi ze-MAC. I-router ichonga idilesi ye-IP, enikezelwa ngumlawuli wenethiwekhi. Yidilesi enengqiqo kwaye idilesi ye-IP inesakhiwo se-hierarchical. Yahlulahlulwe ngokwamanani womnatha kunye namanani omkhosi, anokusetyenziswa ngokulula ukwahlula ii-subnets. Umsebenzi ophambili we-router kukusebenzisa ukudibanisa kwiinethiwekhi ezahlukeneyo

Umahluko 2:Imidiya kunye nolawulo losasazo lwahlukile. Ukutshintsha kwe-Ethernet kunokunciphisa kuphela i-domain yokungqubana, kodwa hayi indawo yosasazo. Inethiwekhi yonke etshintshiweyo yi-domain enkulu yosasazo, kwaye iipakethi zokusasaza zisasazwa kuwo wonke umnatha otshintshiweyo. I-router inokuhlukanisa i-domain yokusasazwa, kwaye iipakethi zokusasaza azikwazi ukuqhubeka zisasazwa nge-router. Ingabonwa ukuba uluhlu lolawulo losasazo lokutshintsha kwe-Ethernet lukhulu kakhulu kunolo lwee-routers, kwaye uluhlu lolawulo losasazo lwee-routers luseluncinci. Njengesixhobo sokuvala ibhuloho, umtshini we-Ethernet unokuphinda ugqibezele ukuguqulwa phakathi kweengqimba zekhonkco ezahlukeneyo kunye neengqimba zomzimba, kodwa le nkqubo yokuguqulwa iyinkimbinkimbi kwaye ayifanelekanga ukuphunyezwa kwe-ASIC, okuya kunciphisa ngokuqinisekileyo isantya sokudlulisa ukutshintshwa.
