Configure VBRP Network Authentication
VBRP has two modes, that is, simple text authentication and MD5 authentication. The set length of the simple text authentication cannot exceed eight authentication words. The set length of the MD5 authentication is the authentication word not exceeding 64 bits.
Configuration Condition
Before configuring the VBRP basic functions, first complete the following task:
Configure VBRP Simple Text Authentication
