The two empty-configured MSR routers MSR-1 and MSR-2 are directly connected through their respective GE0/0 interfaces, and the IP addresses on GE0/0 of MSR-1 and MSR-2 are 10.1.1.1/24 and 10.1.1.2. /24, there is IP reachability between two GE0/0 interfaces.
Then added the following OSPF configurations on the two routers:
MSR-1:
[MSR-1-ospf-1] area 0.0.0.255
[MSR-1-ospf-1-area-0.0.0.255] network 10.1.1.0 0.0.0.255
MSR-2:
[MSR-2-ospf-1] area 255
[MSR-2-ospf-1-area-0.0.0.255] network 10.1.1.0 0.255.255.255
Then the correct description of the above configuration is _____. (Multiple choice)
