You design an iSCSI IPv6 network that contains servers and storage devices. In this network, some servers use link-local addresses.
In this situation, you encounter an issue in which multiple gateways try to create separate storage subnets to isolate the traffic. However, the subnets are redundant.
To work around this issue, configure the initiator and the target on different subnets.
