Virtual Switch Redundancy Protocol (VSRP)

NOTE: This feature cannot be configured in the H2R image in software release 07.6.01b. However, devices
running version 07.6.01b of the H2R image can still be VSRP-aware. (VSRP awareness is described in the
following section.)
Virtual Switch Redundancy Protocol (VSRP) is an HP proprietary protocol that provides redundancy and sub-
second failover in Layer 2 and Layer 3 mesh topologies. Based on the HP Virtual Router Redundancy Protocol
Extended (VRRPE), VSRP provides one or more backups for a Routing Switch. If the active Routing Switch
becomes unavailable, one of the backups takes over as the active device and continues forwarding traffic for the
network.
You can use VSRP for Layer 2, Layer 3, or for both layers. On Routing Switches, Layer 2 and Layer 3 share the
same VSRP configuration information.
Figure 10.7 shows an example of a VSRP configuration.
