Hi!

I don´t know if I understand your question or configuration completely.

If you have 2 iSCSI switches and want to connect 2 bonded NICs to each switch your configuration could be

NIC1 IP 192.168.1.1/24
NIC2 IP 192.168.2.1/24

and the bonded IP to the first switch e.g.

192.168.10.1/24

with "balance-rr"

plus

NIC3 IP 192.168.3.1/24
NIC4 IP 192.168.4.1/24

and the bonded IP to the first switch e.g.

192.168.20.1/24

with "balance-rr".

The important part is that each "physical" IP plus each bonded IP are in a separate network.
