478 CHAPTER 26: I NTEGRATED IS-IS CONFIGURATION COMMANDSExample# When interface Vlan-interface 10 is connected with a non-backbone router inthe same area, you can set this interface as level-1, prohibiting the sending andreceiving of Level-2 Hello packets.[SW8800] interface Vlan-interface 10[3Com-Vlan-interface10] isis enable[3Com-Vlan-interface10] isis circuit-level level-1isis cost Syntaxisis cost value [ level-1 | level-2 ]undo isis cost [ level-1 | level-2 ]ViewInterface viewParametervalue: Specifies the link cost used in the SPF calculation of corresponding level. Itsrange 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-2DescriptionUse the isis cost command to configure the link cost of this interface whenperforming 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 thedefault value.The user is recommended to configure the appropriate link cost for all theinterfaces. Otherwise, the link cost in the calculation of IS-IS routes cannot reflectthe link cost.Example# Set the link cost of the Level-2 link on Interface Vlan-interface 10 to 5.[SW8800] interface Vlan-interface 10[3Com-Vlan-interface10] isis cost 5 level-2isis dis-priority Syntaxisis dis-priority value [ level-1 | level-2 ]undo isis dis-priority [ level-1 | level-2 ]ViewInterface view
