Usage guidelines
The password in the specified mode is inserted into all outbound Level-1 packets (LSP, CSNP, and PSNP)
and is used to authenticate inbound Level-1 packets.
Area authentication enables IS-IS to discard routes from untrusted routers.
Routers in an area must have the same authentication mode and password.
If neither ip nor osi is specified, OSI-related fields are checked.
For security purposes, all passwords, including passwords configured in plain text, are saved in cipher
text.
Examples
# Configure the area authentication mode as simple, and set the plaintext password to 123456.

Usage guidelines
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. For other cost styles, Table 50 a
pplies.
