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?
A.
Add the overload parameter to each device’s OSPF configuration.
B.
Issue the clear ospf database purge command on R1.
C.
Issue the clear ospf neighbor command on R2.
D.
Configure the OSPF lsa-refresh-interval parameter to 0 on each device.
what happens when clear ospf database purge command is issued:
1) The router marks all LSAs as MAXAGE and sends them out.
2) The actual originators of those LSAs now receive these LSAs and re-originate them.
3) Effectively you’re refreshing the OSPF database of the whole area.
