Use area-authentication send-only to disable authentication for incoming ISIS-SPB topology advertisement packets (LSPs, CSNPs, and PSNPs).
Use undo area-authentication send-only to restore the default.
Syntax
area-authentication send-only
undo area-authentication send-only
Default
ISIS-SPB authenticates incoming topology advertisement packets if area authentication (area-authentication-mode) is configured. The device accepts a topology advertisement packet only if the authentication method and password in the packet match its local authentication settings.

Usage guidelines
Before you change area authentication settings for an SPBM network, configure this command to prevent temporary authentication setting mismatch from causing topology advertisement packets to be dropped.
For security purposes, restore the default to authenticate incoming topology advertisement packets after you change area authentication settings across the SPBM network.
This command does not affect outgoing topology advertisement packets. When area authentication is enabled, outgoing ISIS-SPB topology advertisement packets always contain authentication information.
Examples
# Disable authentication for incoming ISIS-SPB topology advertisement packets.
