With the DR/BDR showing on the State, this simply suggest that the OSPF network types were a BROADCAST.ģ. Check that the OSPF neighbors were formed:Īs observed, OSPF neighbors were formed and R5 is showinga s the DR or designated router.

ALl the loopbacks needs to be advertise on both R3 and R6. To explore the ways to enable OSPF, both R3 and R5 will be using the network statement to enable OSPF while for R5 and R6, OSPF will be enabled under interface mode. R3 and R5 will be in OSPF area 35 while R5 and R6 will be in OSPF area 56.

I will be using the below topology to explore on this lab but for this particular concepts, I will just be using R3, R5 and R6 for this lab both on OSPF process 1. On this post, I wlll be exploring concepts of OSPF network Types and look into some details of some attributes required to established OSPF neighbors.
