Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Kana DR yazvino 'ikadzikira' BDR yazvino inova DR itsva uye sarudzo itsva inoitwa kuti iwane imwe BDR. Kana DR itsva ipapo 'anoenda pasi' uye yepakutanga DR zvino iripo, achiri kare akasarudzwa BDR achava DR. DR kuti ariko nechinangwa yokuderedza samambure motokari nokupa tsime routing inogadziridza. DR inochengeta tafura yakakwana ye topology yemambure uye inotumira zvigadziridzo kune mamwe ma routers kuburikidza ne multicast. Vose routers vari vakawanda-kuwana samambure chidimbu kuchaita kuumba muranda / tenzi ukama pamwe DR. Vachaita kuumba adjacencies pamwe DR uye BDR chete. Nguva imwe neimwe iyo router inotumira chinovandudza, inoitumira kuDR uye BDR pane kero ye multicast 224.0.0.6. DR ipapo ichatumira gadziridzo yacho kune mamwe maruta ose ari munharaunda yacho, kukero yemulticast 224.0.0.5. Nenzira iyi ma routers ose haafaniri kugara achigadziridza mumwe nomumwe, uye panzvimbo pezvo anogona kuwana magadziridzirwo awo ose kubva kunzvimbo imwe chete. Kushandiswa kwokuparadzira kwakawanda kunoderedzazve mutoro wenetwork. DRs uye BDRs nguva dzose setup / akasarudzwa pamusoro OSPF nhepfenyuro network. DR dzinogonawo kusarudzwa paNBMA (Non-Broadcast Multi-Access) network dzakadai seFram Relay kana ATM. DRs kana BDRs havasi vakasarudzwa pamusoro pfungwa-to-pfungwa Links (akadai pfungwa-to-pfungwa WAN kubatana) nokuti routers maviri kumativi ose kubatana anofanira kuva zvachose pedyo uye bandwidth pakati pavo hazvigoni mberi optimized. DR nevasiri-DR routers vanoshanduka kubva ku2-nzira kusvika kuzere hukama hwepedyo nekutsinhana DD, Chikumbiro, uye Gadziridza.  Mubvunzo: Ndezvipi zvinhu zviviri bedzi zvinogadzira miganhu yakabatana nazvo?
