Which statement about the designated router (DR) and backup designated router (BDR) in an OSPF multi-access network is true?
Which statement about the designated router (DR) and backup designated router (BDR) in an OSPF multi-access network is true?
In an OSPF multi-access network, non-designated and non-backup designated routers (commonly known as DROTHERs) send link state updates and acknowledgements to the special multicast address 224.0.0.6, which is designated for all DR and BDR routers. This ensures that the DR and BDR receive the necessary information to maintain the network topology. This is a crucial aspect of OSPF where efficient communication and organization help in scaling and maintaining the network operations.
The answer is D
https://community.cisco.com/t5/switching/dr-bdr-ospf/td-p/2010995 "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."
Answer D. p365 + p366 "224.0.0.6 AllDRouters : All other routers send LSA updates and acknowledgements
