The two empty MSR routers are connected by the way shown in the figure. By configuring the IP address, the GE0 / 0 interfaces of the two routers can communicate with each other.

The two empty MSR routers are connected by the way shown in the figure. By configuring the IP address, the GE0 / 0 interfaces of the two routers can communicate with each other.

Now the following configurations are added to the two routers:

RTA:

[RTA]ospf

[RTA-ospf-1]area 0

[RTA-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.3

[RTA-GigabitEthernet0/0]ospf dr-priority 2

DAF:

[RTB]ospf [RTB-ospf-1]area 0

[RTB-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.3

[RTB-GigabitEthernet0/0]ospf dr-priority

Then after the OSPF neighbor state is stable, ______ .
A . OSPF interfaces have the same priority, and no OSPF DR election is performed on the 192.168.1.0/30 network segment
B . Of the two routers, one is DR and one is BDR
C . Of the two routers, one is DR and the other is DRother
D .  The neighbor status of the two routers is FULL and 2-Way

Answer:   B

Explanation:

[ Interface ] ospf dr-priority ( 0-255 ) modify the interface priority, the default is 1 , the non-participation election with priority 0 is only broadcast network, NBMA network only has DB , BDR election, Gigabit Ethernet default interface Broadcast modify ospf network type: [ interface ] ospf network-type () DR , BDR election is for the interface, network segment, not RT is DR , BDR . By comparing the interface priority (the bigger the better), the router id is the same (the bigger the better) the other DR2 status stays at 2-way
