Re: LAN Redudancy problem

Hello ardi,

Why do you have this kind of configuration? It makes no sense for me.

Using 2 NIC's on the same network segment on each machine has only disadvantages,
also if you have a server OS use it's DNS role and configure all machines
with one LAN ip address, default gateway(if external access [internet for
example] is needed) and DNS server ip address.

So please describe why you configure 2 switches in a loop within the same
subnet.

Best regards
