cluster, HA Network setting

[simonchoi]

Hello, I have a question about network settings in Proxmox VE.

Can it be configured in the following way?

1. When a VM needs external internet, it goes through 'Switch 1'.
2. When a VM needs internal internet (e.g., for clustering, HA), it goes through 'Switch 2'.
3. If 'Switch 2' fails, then it should switch to using 'Switch 1' for internal internet as well.

Should VM be assigned the IP of 'Switch 1'? Or should it be assigned the IP of 'Switch 2'?"

To answer your questions,

1. When a VM needs external internet, it goes through 'Switch 1'.
   => Yes, you could.
2. When a VM needs internal internet (e.g., for clustering, HA), it goes through 'Switch 2'.
   => Yes, you could
3. If 'Switch 2' fails, then it should switch to using 'Switch 1' for internal internet as well.
   => Technically this is possible, but you have to change your setup, and draw different picture than your current one.
