FIGURE 12 VSRP priority
However, if one of the VRID ports goes down on one of the Backups, that Backup priority is reduced. If
the Master priority is reduced enough to make the priority lower than a Backup priority, the VRID fails
over to the Backup. The following figure shows an example.
FIGURE 13 VSRP priority recalculation
You can reduce the sensitivity of a VSRP device to failover by increasing its configured VSRP priority.
For example, you can increase the configured priority of the VSRP device on the left in
Figure 13 to
150. In this case, failure of a single link does not cause failover. The link failure caused the priority to be
reduced to 100, which is still equal to the priority of the other device. This is shown in the following
figure.
