+下面的输出展示了如何配置VRRP的跟踪，引用了对象1, 该被跟踪对象对`Loopback0`接口的线路协议进行跟踪：
 
+```
+VTP-Server-1(config)#track 1 interface Loopback0 line-protocol
+VTP-Server-1(config-track)#exit
+VTP-Server-1(config)#interface vlan192
+VTP-Server-1(config-if)#vrrp 1 track 1
+VTP-Server-1(config-if)#exit
+```
+
+而下面的输出则展示了如何将VRRP配置为对引用对象2的追踪，此被追踪对象追踪了到前缀`1.1.1.1/32`的可达性。一个被追踪的IP路由对象在存在一个该路由的路由表条目时，被认为是在线且可达的，同时该路由不是无法访问的（无法访问就是说有着255的路由度量值）, 当发生无法访问时，该路由就会从路由信息数据库中被移除（a tracked IP route object is considered to be up and reachable when a routing table entry exists for the route and the route is not accessible(i.e., has a route metric of 255)，in which case the route is removed from the Routing Information Base(RIB) anyway）。
+
+```
+VTP-Server-1(config)#track 2 ip route 1.1.1.1/32 reachability
+VTP-Server-1(config-track)#exit
+VTP-Server-1(config)#interface vlan192
+VTP-Server-1(config-if)#vrrp 1 track 2
+```
+
+VRRP跟踪的配置，是通过使用命令`show vrrp interface [name]`命令进行验证的。下面的输出对此进行了演示：
+
+<pre>
+VTP-Server-1#show vrrp interface vlan192
