Usage guidelines
The configured password in the specified mode is inserted into all outgoing Level-2 packets (LSP, CSNP,
and PSNP) and is used for authenticating the incoming Level-2 packets.
All the backbone routers must have the same authentication mode and password.
If neither ip nor osi is specified, the OSI-related fields in LSPs are checked.
For security purposes, all passwords, including passwords configured in plain text, are saved in cipher
text.
Examples
# Configure the routing domain authentication mode as simple, and set the plaintext password to
123456 .
