Use the area-authentication-mode command to specify the area authentication mode and a 

password.  

Use the undo area-authentication-mode command to restore the default. 

No area authentication is configured by default.  

The password in the specified mode is inserted into all outgoing Level-1 packets (LSP, CSNP and 

PSNP) and is used for authenticating the incoming Level-1 packets. 

With area authentication configured, IS-IS discards incoming routes from untrusted routers.

Use the auto-cost enable command to enable automatic link cost calculation.  

Use the undo auto-cost enable command to disable the function. 

This function is disabled by default. 

After automatic link cost calculation is enabled, the link cost is automatically calculated based on the 

bandwidth reference value of an interface. When the cost-style is wide or wide-compatible, the cost 

value of an interface is calculated by using the formula: Cost = (reference bandwidth value/link 

bandwidth) × 10.
