Hi mack1982,

Can you please explain me about how to achieve a fully redundant private network with 2 dedicated switches (so that neither the port, nor the cables, nor the switches become a single point of failure)?

We connect eth2 from both nodes to switch1 and eth2 from both nodes to switch2. So 2 completely redundant paths. How should we proceed from here? We configure IPMP on these 2 interfaces. But it does not look correct.
So should there be a cross or straight cable between switch1 & switch2?
Should the IP Address assigned to 4 ports (eth2 & eth3 on both nodes) should belong to the same LAN or different LAN? i.e. all 4 from 192.168.2.x or eth2 has to be from 192.168.2.x and eth3 has to be from 192.168.3.x? If 2 diff. LAN then will IPMP work on it? If 1 LAN then we would need a cross cable between switches to make it 1 network else all 4 IPs cant ping/see each other. So as you see, i am confused and it would be great if you can help me understand this.

many thanks.
