md5: Specifies MD5 authentication.

cipher: Specifies a password in encrypted form.

plain: Specifies a password in plaintext form. For security purposes, the password specified in plaintext form will be stored in encrypted form.

Usage guidelines

ISIS-SPB area authentication guarantees that SPBM nodes learn topology data only from trustworthy neighbors.

For correct authentication, make sure the authentication method and password are the same across the SPBM network. ISIS-SPB sends these authentication settings in topology advertisement packets (LSPs, CSNPs, and PSNPs). The recipients accept a topology advertisement packet only if the authentication settings in the packet match their local authentication settings.

Example

# Set the area authentication method to simple and the password to 123456 in plain text.

<Sysname> system-view
[Sysname] spbm
[Sysname-spbm] area-authentication-mode simple plain 123456
