Authentication

Simple authentication of VRRP packets ensures that only trusted routers participate in VRRP processes. When you enable authentication, OS10 includes the password in its VRRP transmission. The receiving router uses that password to verify the transmission.

You must configure all virtual routers in the VRRP group with the same password. You must enable authentication with the same password or authentication is disabled. Authentication for VRRPv3 is not supported.

  1. Create a virtual router for the interface with the VRRP identifier in INTERFACE mode (1 to 255).
    vrrp-group 
                                           vrrp-id
                                        
  2. Configure a simple text password in INTERFACE-VRRP mode.
    authentication-type simple—text 
                                           text [
                                           auth-text]
                                        
    • simple—text text — Enter the keyword and a simple text password.
    • auth-text — (Optional) Enter a character string up to eight characters long as a password.

Configure VRRP authentication

OS10(config)# interface ethernet 1/1/5
                                 OS10(conf-if-eth1/1/5)# vrrp-group 250
                                 OS10(conf-eth1/1/5-vrid-250)# authentication simple-text eureka
                                 
                              

Verify VRRP authentication configuration

OS10(config)# interface ethernet 1/1/1
                                 OS10(conf-if-eth1/1/1)# vrrp-group 1
                                 OS10(conf-eth1/1/1-vrid-1)# authentication simple-text dell
