Overview of Virtual Switch Redundancy Protocol (VSRP)
VSRP is a Brocade proprietary protocol that provides redundancy and sub-second failover in Layer
2 and Layer 3 mesh topologies. Based on the Brocade’s proprietary Virtual Router Redundancy
Protocol Extended (VRRPE), VSRP provides one or more backups for the device. If the active device
becomes unavailable, one of the backups takes over as the active device and continues forwarding
traffic for the network.
Layer 2 and Layer 3 share the same VSRP configuration information.
Figure 75 shows a VSRP configuration.
