What are three types of OSPF packets? (Choose three.)

Your OSPF network consists of five Junos devices, R1 through R5, all in Area 0. You want to reset
the LSDB for the entire area.
Which action accomplishes this task?

Your Junos device runs OSPF and BGP. You must limit the number of BGP prefixes within the
10.0.0.0/8 address block to be redistributed into OSPF.
Which parameter would help to control this potential problem?

Referring to the exhibit, which two statements are true? (Choose two.)

— Exhibit —
[edit protocols ospf]
user@R1# show

— Exhibit —
You are using traceoptions, configured as shown in the exhibit, to monitor regular OSPF
communications between R1 and R2 in real time. However, you are not seeing the desired
information.
How would you resolve this problem?
