Conguring VRRP Authentication
Simple authentication of VRRP packets ensures that only trusted routers participate in VRRP processes.
When you enable authentication, the Dell Networking OS includes the password in its VRRP transmission. The receiving router uses that
password to verify the transmission.
NOTE
: You must congure all virtual routers in the VRRP group the same: you must enable authentication with the same
password or authentication is disabled.
To congure simple authentication, use the following command.
NOTE
: Authentication for VRRPv3 is not supported.
• Congure 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.
Example of authentication-type Command
The bold section shows the encryption type (encrypted) and the password.
