Parameter
value: Specifies the link cost value for corresponding SPF calculation, in the range of
0 to 63. It is 10 by default.
level-1: Indicates the link cost corresponding to Level-1 layer.
level-2: Indicates the link cost corresponding to Level-2 layer.
Description
Use the isis cost command to set the interface link cost for SPF calculation.
Use the undo isis cost command to resume the default link cost value.
If neither level-1 nor level-2 is assigned in the configuration, then both level-1 and
level-2 are configured by default.
You are recommended to configure a proper link cost for each interface; otherwise,
the link cost for IS-IS route calculation may not reflect the correct cost.
Example
# Set the Level-2 link cost to 5 for Vlan-interface10.
