DROther routers stay in the 2WAY state with each other and do not interact with each other for routing information. After clearing the OSPF process on R1 and viewing the neighbor relationships on R1 again, the following is displayed: rl#clear ip ospf process Reset ALL OSPFprocesses?[no]:PriState DeadTimeAddress 123.1.1.2 0 FULL/DROTHER 00:00:38 123.1.1.2 FastEthernetO/O 123.1.1.3 0 FULL/DROTHER 00:00:39 123.1.1.3 FastEthernetO/ O 123.1.1.2 0 FULL/ -00:00:38 12.1.1.2As you can see from the above output, after R1 restarts the OSPF process, R1 is still DR, R2 and R3 are still DROther, and there is no BROther in the networks of Rl, R2 and R3.If R1 fails, R2 and R3 will not be able to interact properly with each other via Ethernet.,... DR BDR DR BDROne statement that must be emphasized is that DR and BDR elections are interface-based -------------------------------------- and not router-based. A router may be a DR in one R1 ___________ spear k segment, or it may also be a BDR in another segment, and R4 Zeus "by R5 may be a DROthero in a third segment In Figure 8-2-8, router ° R2 is a BDR in the R1 and R2 segments, and it is a router in the R2 and R3 segments Figure 8-2.8 Multiple identity router251 ,
