Virtual Switch Redundancy Protocol (VSRP)

In this section:

1. VSRP Overview
2. VSRP Configuration Notes and Feature Limitations
3. VSRP Redundancy
4. Master Election and Failover
5. VSRP Interval Timers
6. Configuring Device Redundancy Using VSRP
   Virtual Switch Redundancy Protocol (VSRP) provides device redundancy in a port-based VLAN. Configuring VSRP device redundancy in your network leads to faster failover times if an interface goes offline.
7. Configuring Optional VSRP Parameters
8. Configuring Authentication on VSRP Interfaces
   If the interfaces on which you configure the VRID use authentication, the VSRP packets on those interfaces must also use the same authentication.
9. Tracking Ports and Setting the VSRP Priority
   Configuring port tracking on an exit path interface and setting a priority on a VSRP device enables VSRP to monitor the interface. If the interface goes down, the VRID’s VSRP priority is reduced by the amount of the track port priority you specify.
