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 secrecy, 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.
<Sysname> system-view
[Sysname] isis 1

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 31
applies.
