2. Start the OSPF process and release the corresponding CIDR Block
★☆R1 ☆★
R1-jin (config )#

R1-jin (config-router) # network 192.168.4.0 0.0.255 area 0 -- | all interfaces of network 192.168.1.0 and 4.0 network segment run OSPF
R1-jin (config-router) # end
R1-jin #
R1-jin # show ip route -- view route table
R1-jin # show ip ospf neighbor -- View neighbor list
R1-jin # show ip ospf interface f1/0 -- View OSPF interface Data Structure
R1-jin # show ip protocols -- view the Protocol that the route runs

★☆R2 ☆★
R2-jin (config )#
R2-jin (config) # router ospf 1
R2-jin (config-router) # network 0.0.0.0 255.255.255.255 area 0 -- Declaration (second method): All interfaces run OSPF
R2-jin (config-router) # end
R2-jin #
R2-jin # show ip route
R2-jin # show ip ospf neighbor
R2-jin # show ip ospf database
R2-jin # show ip ospf interface f1/0
R2-jin # show ip ospf interface f0/0
R2-jin # show ip protocols

★☆R3 ☆★
R3-jin (config )#
R3-jin (config) # router ospf 1
R3-jin (config-router) # network 192.168.5.2 0.0.0.0 area 0 -- | Declaration (Third Way ):
R3-jin (config-router) # network 192.168.3.1 0.0.0.0 area 0 -- | specify 192.168.5.2, 3.1 interface to run OSPF
R3-jin (config-router) # end
R3-jin #
R3-jin # show ip route
R3-jin # show ip ospf neighbor
R3-jin # show ip ospf database
R3-jin # show ip ospf interface s1/0
R3-jin # show ip protocols

OK !!! The experiment is successfully completed !!!

 
All the tools I use are the "Xiao fan Simulator ".
The operation is the same as that of a real device. Apart from several commands, you can discover them slowly!
