Failure of the primary interconnect path results in intra-cluster communications occurring over the redundant dedicated interconnect path. When Cluster Server is configured to send intra-cluster communication over the LAN NIC as well, the cluster nodes will still have a working communication path even if one of the dual-ported NICs fails.
