The following example use cases are supported by the Cisco ITD feature:
Load-balance traffic to 256 servers of 10Gbps each.
Load-balance to a cluster of Firewalls. ITD is much superior than policy-based routing (PBR).
Health of an Interface Connected to a Node
ITD leverages the IP service level agreement (IP SLA) feature to periodically probe each node. The probes are sent at a one second frequency and sent simultaneously to all nodes. You can configure the probe as part of the cluster group configuration. A probe is declared to have failed after retrying three times.
