★☆R1☆★
R1-jin#
R1-jin#config terminal
R1-jin(config)#router ospf 1
R1-jin(config-router)#area 1 nssa
R1-jin(config-router)#end

R1-jin#show ip route
Press RETURN to get started., 1 subnets
C       1.1.1.1 is directly connected, Loopback0
C    10.0.0.0/8 is directly connected, FastEthernet0/0
C    192.168.0.0/24 is directly connected, FastEthernet1/0
R1-jin#

★☆R2☆★
R2-jin#
R2-jin#config terminal
R2-jin(config)#router ospf 1
R2-jin(config-router)#area 1 nssa
