H3C S7500 Series Ethernet Switches Chapter 4 Integrated IS-IS Configuration Commands
4-2
Description
Use the area-authentication-mode command to configure IS-IS to authenticate the
packets (LSP, CSNP and PSNP) received from level-1 route using the predefined mode
and password.
Use the undo area-authentication-mode command to disable IS-IS from
authenticating the received packets.
The system will neither authenticate the packets received from level-1 route nor check
its password by default.
We can use this command to clear all level-1 routing packets not compatible with the
area authentication password set by the command. And at the same time, we also
instruct the system to follow a specific mode to insert the area authentication password
in all the level-1 routing packets sent from the local node.
Related commands: reset isis all, domain-authentication-mode, isis
authentication-mode.
Examples
# Set the area authentication password to hello, and the authentication mode to simple.
