Virtual Switch Redundancy Protocol (VSRP)
Virtual Switch Redundancy Protocol (VSRP) is a Foundry proprietary protocol that provides redundancy and sub-
second failover in Layer 2 and Layer 3 mesh topologies. Based on the Foundry Virtual Router Redundancy
Protocol Extended (VRRPE), VSRP provides one or more backups for a Layer 2 Switch or Layer 3 Switch. If the
active Layer 2 Switch or Layer 3 Switch becomes unavailable, one of the backups takes over as the active device
and continues forwarding traffic for the network.
The FastIron family of switches support full VSRP as well as
VSRP-awareness
. A Foundry device that is not
itself configured for VSRP but is connected to a Foundry device that is configured for VSRP, is
VSRP aware
.
You can use VSRP for Layer 2, Layer 3, or for both layers. On Layer 3 Switches, Layer 2 and Layer 3 share the
same VSRP configuration information. On Layer 2 Switches, VSRP applies only to Layer 2.
NOTE:
VSRP and 802.1Q-n-Q tagging are not supported together on the same device.
Figure 8.7 shows an example of a VSRP configuration.
