HP VPN Firewall Appliances Network Management Command Reference

Usage guidelines
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.
Routers in a common area must have the same authentication mode and password.
If neither ip nor osi is specified, OSI related fields are checked. Whether a password should use ip or osi
is not affected by the actual network environment.
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 ivg.
<Sysname> system-view

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

value of an interface is calculated by using the formula: Cost = (reference bandwidth value/link
bandwidth) × 10, ranging from 1 to 16777214. For other cost styles, Table 79 a
