Cost-Style - 3Com 7750 Series Command Reference Manual

3Com Switch 7750 Series
Command Reference Guide – Routing Protocol
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 above.
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 leve-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 command: reset isis all, domain-authentication-mode, and isis
authentication-mode.
Example
# Set the area authentication password to hello, and the authentication mode to
simple.
<3Com> system-view
System View: return to User View with Ctrl+Z.
[3Com] isis
[3Com-isis] area-authentication-mode simple hello
