Dell SmartFabric OS10 User Guide Release 10.5.3

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, from 1 to 255.

   vrrp-group vrrp-id

2. Configure a simple text password in INTERFACE-VRRP mode.

   authentication-type simple—text text

   simple—text text — Enter the keyword and a simple text password.

   NOTE: The system does not support a simple text password that begins with the ! or # character. Ensure that the password does not begin with either of these characters.

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
