Configuring 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 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.

  • NOTE: Authentication for VRRPv3 is not supported.
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.
