ospf part2

OSPF is

• widely used routing protocol on the live network.

• commonly used routing protocol on the network security.

• non-used routing protocol on the live network.

What are the basic concepts of OSPF?

• mac address, area, OSPF neighbor table, LSDB table, and OSPF routing table

• router ID, area, OSPF neighbor table, LSDB table, and OSPF routing table

• router ID, area, OSPF neighbor table, and OSPF routing table

• mac address, area, OSPF neighbor table, DBLStable, and OSPF routing table

Create and run an OSPF process.

• ospf [ router-id | router-id router-id ]

• ospf [ process-id | router-id router-id ]

• ospf [ process-id | router-id wildcard-mask]

Set an OSPF interface cost.

[Huawei-GE1/0/1] ospf cost cost

• The cost value is an integer ranging from 1 to 2147483648

• The cost value is an integer ranging from 1 to 65535.

• The cost value is an integer ranging from 1 to 26884

wildcard-mask
0.0.0.255 indicates that the mask length is

• 27 bits

• 32 bits

• 24 bits

• 28 bits

[Huawei-GigabitEthernet0/0/0] ospf dr-priority priority

• The value ranges from 0 to 134

• The value ranges from 0 to 128

• The value ranges from 0 to 255
