Exam 200-301 topic 1 question 447 discussion

The subnet mask seems wrong. Because the wildcard for a /30 should be 0.0.0.3, not 0.0.0.255.

just needs to match, not be identical

C is correct

The Wildcard mask should be 0.0.0.3. The OSPF priority on a point-to-point link is zero

Yes, option 'c' is correct. There appears to be some conjecture about the mismatch in wildcard mask - let me clear it up. Note that the wildcard mask in the answer doesn’t match that in the graphic. This is OK – don’t panic. The network command is used to define the range of addresses owned by the router that will participate in the OSPF routing process. Above, if an interface is between 10.0.0.1 and 10.0.0.254, it participates in OSPF, area 0. It just so happens that interface Serial 0/1 is the only interface owned by the router that qualifies for this inclusion.

Router ID and priority are set automatically. We need to use router ospf <process-id> command to get into the OSPF configuration and then network <network> <Wild-card mask> area <area-id> on both routers. The answer is C but the WCM should be 0.0.0.3 https://networklessons.com/ospf/basic-ospf-configuration

I GUESS IT'S A TYPO FOR SUBNET MASK OF 255.255.255.252 , WILDCARD MASK SHOULD BE 0.0.0.3

Ip wild card dont much the adjacency could not much

Confusing.. I thought /30 wild mask is 0.0.0.3 I don't think /24 is appropriate can someone explain better please?

ospf command = look for answer with wildcard

Despite what the wildcard says and the other answers, the other commands won't configure an OSPF connection with each other.
