This enumerated value (enable or disable, defaulting to disabled) controls whether a virtual router in the master state will accept packets addressed to the address owner's IP as if it were its own, even when this router is not the actual address owner. An admin enables it in deployments where pinging or managing the virtual IP directly is required even from a non-owner master. For example, enabling accept mode lets network staff successfully ping the VRRP virtual IP address even when the currently active master isn't the router that owns that address.
