Parameter 
value: Specifies the link cost used in the SPF calculation of corresponding level. Its 
range is 1 to 63. By default, the value is 10. 
level-1: Indicates that the link cost corresponds to Level-1.  
level-2: Indicates that the link cost corresponds to Level-2  
Description 
Use the isis cost command to configure the link cost of this interface when performing 
SPF calculation. 
Use the undo isis cost command to restore the default link cost.  
If neither Level 1 nor Level 2 is specified in the configuration, Level-1 will be the default 
value.  
The user is recommended to configure the appropriate link cost for all the interfaces. 
Otherwise, the link cost in the calculation of IS-IS routes cannot reflect the link cost. 
Example 
# Set the link cost of the Level-2 link on Interface Vlan-interface 10 to 5.  
[Quidway] interface Vlan-interface 10 
[Quidway-Vlan-interface10] isis cost 5 level-2
