The tVrrpOpTracerouteReply is valid only if the VRRP virtual router
instance associated with this entry is a non-owner.
By setting tVrrpOpTracerouteReply to 'true', a non-owner master is
enabled to reply to traceroute requests directed to the virtual
router instance IP addresses.
A non-owner backup virtual router never responds to such traceroute
requests irrespective of the value of tVrrpOpTracerouteReply.
