You are asked to configure the OSPF environment to prevent the DRother routers from participating
in DR/BDR election.
Referring to the exhibit, which command will accomplish this task?

Option B
B over D here. Setting the OSPF priority to 0 (option B) on a specific interface means that router won't participate in DR/BDR elections, but others still can. D changes the whole interface type to p2p, which avoids any election entirely, not just for DRothers. I think B matches what they're asking for, but I get why D seems tempting from the wording.
B tbh
Yeah, it's B. Setting OSPF priority to 0 stops that interface from joining DR/BDR elections. Seen this in a few labs, never had issues with it. Anyone got a different config for this scenario?
Yeah, pretty sure it's B since setting the OSPF priority to 0 keeps that interface out of the DR/BDR election. That's usually how you turn a router into just a DRother without messing up DR elections for the rest of the segment. If they wanted no elections at all, p2p would be more correct. Agree?
Its B
B , priority 0 keeps that router out of DR/BDR election per Junos docs.
B/C? I see why C looks tempting since NBMA types use DR/BDR too, but in Junos for blocking just participation it's setting priority to 0 like B. Trap is thinking you change network type when you only want to exclude a router. Seen similar wording in exam reports.
B not C. Had something like this in a mock, pretty sure priority 0 is what Junos wants for stopping DRother participation.
Not D. Setting interface-type to p2p would avoid DR/BDR elections entirely, but the question asks to prevent DRother routers from participating in elections-not make the segment p2p. B (priority 0) is what Junos and most OSPF books say for this use case. Happens a lot on multi-access segments, pretty sure that's what they're testing.
Be respectful. No spam.
