Configuring VRRP Authentication
Simple authentication of VRRP packets ensures that only trusted routers participate in VRRP processes.
When you enable authentication, Dell Networking OS includes the password in its VRRP transmission.
The receiving router uses that password to verify the transmission.\
NOTE: You must configure all virtual routers in the VRRP group the same: you must enable
authentication with the same password or authentication is disabled.
To configure simple authentication, use the following command.
• Configure a simple text password.
INTERFACE-VRID mode
authentication-type simple [encryption-type] password
Parameters:
– encryption-type: 0 indicates unencrypted; 7 indicates encrypted.
– password: plain text.
