Table 46: Interface State and Priority Cost Usage
Priority Cost UsageTracked Interface State
priority-cost priorityDown
Priority-cost of the lowest applicable bandwidth
threshold
Not down; media speed below one or more
bandwidth thresholds
You must configure an interface priority cost only if you have configured no bandwidth
thresholds. If you have not configured an interface priority cost value, and the interface
is down, the interface uses the bandwidth threshold priority cost value of the lowest
bandwidth threshold.

Configuring a Route to Be Tracked
VRRP can track whether a route is reachable (that is, the route exists in the routing table
of the routing instance included in the configuration) and dynamically change the priority
of the VRRP group based on the reachability of the tracked route, triggering a new master
router election.
To configure a route to be tracked, include the following statements:
track {
priority-hold-time seconds;
route prefix/prefix-length routing-instance instance-name priority-cost priority;
}
