osi: Specifies to check the OSI related fields in a LSP.

Whether a password should use ip or osi is not affected by the actual network 
environment.

Use the domain-authentication-mode command to configure the routing 
domain authentication mode to insert the area authentication password into all 
the sent level-2 packets (LSP, CSNP, and PSNP) in the predefined way and verify the 
authentication password of the received level-2 pockets.

Use the undo domain-authentication-mode command to cancel the routing 
domain authentication mode configuration.

By default, no routing domain authentication mode is configured in the system; 
that is, the system authenticates no level-2 packets received and is configured with 
no password.

# Use the simple mode and password “123456” to authenticate level-2 routing 
packets.
