You specify the route to be tracked by its address and prefix-length values. Optionally, for an IPv4 route, you can enter a VRF instance name if the route is part of a VPN routing and forwarding (VRF) table. The next-hop address is not part of the definition of a tracked IPv4/ IPv6 route. 568 Object Tracking
