Which two statements are correct about OSPF route summarization? (Choose two.)

Automatic OSPF route summarization is performed by the ABR.
The metric of the summary route is equal to the lowest cost network within the summary address range.
The area 51 range 172.0.0.0 255.0.0.0 command identifies area 51 as the area that contains the range of networks to be summarized.
OSPF can perform automatic summarization on major classful network boundaries even if no summarization commands are entered from the CLI.
Once OSPF route summarization is configured, the summary route will be advertised even if none of the networks in the address range are in the routing table.
