15 Overview of Virtual Switch Redundancy Protocol (VSRP) 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 76 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 Figure 77. FIGURE 77 VSRP priority bias Configured priority = 150 Actual priority = 150 * (2/3) = 100 Configured priority = 100 Actual priority = 100 * (3/3) = 100 VSRP Master optional link VSRP Backup Link down FF F X B BB VSRP Aware VSRP Aware VSRP Aware Track ports Optionally, you can configure track ports to be included during VSRP priority calculation. In VSRP, a track port is a port that is not a member of the VRID's VLAN, but whose state is nonetheless considered when the priority is calculated. Typically, a track port represents the exit side of traffic received on the VRID ports. By default, no track ports are configured. 416 BigIron RX Series Configuration Guide 53-1001810-01
