Which three configuration statements accomplish this task?

After a recent power outage, your manager asks you to investigate ways to automatically reduce the impact caused by suboptimal routing in your OSPF and OSPFv3 network after devices reboot.

Which three configuration statements accomplish this task? (Choose three.)
A . set protocols ospf overload timeout 900
B . set protocols ospf3 realm ipv4-unicast overload timeout 900
C . set protocols ospf overload
D . set protocols oapf3 overload timeout 900
E . set protocols ospf3 overload

Answer: A,B,D

Explanation:

In OSPF and OSPFv3, the "overload" status can be set on a router to signal to other routers in the network that it should not be considered as a transit router for a certain period of time or until certain conditions are met. This can help to reduce the impact of suboptimal routing following a device reboot, as it gives the router time to fully converge its routing table. The configuration statements to accomplish this are:

set protocols ospf overload timeout 900. This sets the OSPF router to advertise itself as "overloaded", which effectively means not to use it for transit traffic, for a period of 900 seconds after the OSPF process starts.

set protocols ospf3 realm ipv4-unicast overload timeout 900. This sets the OSPFv3 process for the IPv4 unicast address family to advertise itself as "overloaded" for a period of 900 seconds after the OSPFv3 process starts.

set protocols ospf3 overload timeout 900. This sets the OSPFv3 router to advertise itself as "overloaded" for a period of 900 seconds after the OSPFv3 process starts.
