NSE7_EFW-7.2 · Question #26
Which statement about the designated router (DR) and backup designated router (BDR) in an OSPF multi-access network is true?
The correct answer is D. Non-DR and non-BDR routers send link state updates and acknowledgements to 224.0.0.6. On the broadcast network, all routers that are NOT a DR or BDR are called DROTHER. DROTHER will send their link state updates and LSAck to the AllDRouter address, 224.0.0.6. https://community.cisco.com/t5/switching/dr-bdr-ospf/td-p/2010995
