Explanation:
Configuring GLBP Weighting: Example

In the following example, Router A, shown in Figure 1, is configured to track the IP routing
state of the POS interface 5/0 and 6/0, an initial GLBP weighting with upper and lower
thresholds is set, and a weighting decrement value of 10 is set. If POS interface 5/0 and 6/0
goes down, the weighting value of the router is reduced.
track 1 interface POS 5/0 ip routing
track 2 interface POS 6/0 ip routing
interface fastethernet 0/0
glbp 10 weighting 110 lower 95 upper 105
glbp 10 weighting track 1 decrement 10
glbp 10 weighting track 2 decrement 10
glbp 10 forwarder preempt delay minimum 60
