Use the area-authentication-mode command to configure ISIS to authenticate 
the received Level-1 routing information packets (LSP, CSNP and PSNP), according 
to the pre-defined mode and password.

Use the undo area-authentication-mode command to configure ISIS not to 
authenticate the said packets.

In default configuration, the system will not authenticate the received Level-1 
routing packets, and there is no password. As the result of this command, no 
Level-1 routing packets whose area authentication passwords are not consistent 
with the one set via this command will be received. At the same time, this 
command will let ISIS insert the area authentication password into all the level-1 
routing packets sent by this node, in a certain mode.

Related command: reset isis all, domain-authentication-mode, isis 
authentication-mode.

# Set the area authentication password as "hello" and the authentication type as 
simple.

narrow: Only receives/sends packets whose cost type is narrow

wide: Only receives/sends packets whose cost type is wide.

compatible: Receives/sends packets whose cost type is narrow or wide.

narrow-compatible: Receives packets whose cost type is narrow or wide, but 
only sends packets whose cost type is narrow

wide-compatible: Receives packets whose cost type is narrow or wide, but only 
sends packets whose cost type is wide.
