By default, a router that is not the IP address owner, but is the master router for another IP address, accepts and responds to pings and accepts a Telnet to that router. Accepting packets sent to the other IP address is a useful tool during verification of network configuration. The vrrp assume-ownership disable command specifies that the router should not assume ownership of the virtual IP address if it is the master router regardless of whether it is the IP address owner, which means that it will not accept packets sent to that IP address during verification of network configuration.This command is ignored (irrelevant) when the router is the IP address owner (section 6.4.3 of RFC 2338, Virtual Router Redundancy Protocol).

The vrrp track interface command ties the priority of the router to the availability of its interfaces. It is useful for tracking interfaces that are not configured for VRRP. Only IP interfaces are tracked. A tracked interface is up if IP on that interface is up. Otherwise, the tracked interface is down.
You can configure VRRP to track an interface that can alter the priority level of a virtual router for a VRRP virtual router. When the IP protocol state of an interface goes down or the interface has been removed from the router, the priority of the backup virtual router is decremented by the value specified in the priority-decrement argument. When the IP protocol state on the interface returns to the up state, the priority is restored.

In the following example, 10-Gigabit Ethernet interface 0/3/0/0 tracks interface 0/3/0/3 and 0/3/0/2. If one or both of these two interfaces go down, the priority of the router decreases by 10 (default priority decrement) for each interface. The default priority decrement is changed using the priority-decrement argument. In this example, because the default priority of the virtual router is 100, the priority becomes 90 when one of the tracked interfaces goes down and the priority becomes 80 when both go down. See the priority command for details on setting the priority of the virtual router.
