Refer to the exhibit. Routers R1 and R3 have the default configuration. The router R2 priority is set to 99. Which commands on R3 configure it as the DR in the 10.0.4.0/24 network?
A.
R3(config)#interface Gig0/0 R3(config-if)#ip ospf priority 100
B.
R3(config)#interface Gig0/0 R3(config-if)#ip ospf priority 1
C.
R3(config)#interface Gig0/1 R3(config-if)#ip ospf priority 0
D.
R3(config)#interface Gig0/1 R3(config-if)#ip ospf priority 100
Answer: D
Explanation:
- Router with the highest OSPF interface priority on a segment becomes the DR.
This is provided using the interface command: ip ospf priority <0 - 255>
The default OSPF priority is 1.
- Router with the next highest OSPF interface priority becomes the BDR.
- If router priorities are equal, the highest Router ID (RID) breaks the tie.
- The OSPF Router ID for a router is found by:
1. The router-id <ip-address> config-router command.
2. If that doesn’t exist, then the highest IP address on a loopback is used.
3. If that doesn’t exist, then the highest IP address on an up physical is used.
are you serious? have you suffer of a recent blow of the head? you don't even understand the question, but you still comment! Answer is not A you dumb ass!!!! stop comment if you don't know shit. Answer is D!
This is not spanning tree protocol where 0 becomes the highest priority.
In the case of OSPF, 0 means you will never be elected as DR or BDR. Default priority is 1.
I would have thought setting the loopback on R3 with a higher priority of 100 would have got DR.Why choose setting the main interface with the higher priority?
Los routers en la red seleccionan como DR al router con la prioridad de interfaz más alta. El router con la segunda prioridad de interfaz más alta se elige como BDR.
