Need help - configuring network interfaces

[r0g]

Hi,

i have 2 Network cards installed into my Proxmox Host. Both are visible in my Proxmox Webinterface and both are bridged to vmbr0 and vmbr1.
They got static IP Adresses:
vmbr0: 192.168.177.30
vmbr1: 192.168.177.6

When i plug out the Network cable of one Interface i can´t ping the other one. So, no matter which interface is plugged off i can´t ping the other one which is plugged in.

Can you help me?
Sorry for bad englisch....

I think you are trying to have redundant links? You need to make use of bond interfaces for this and add the bridge on top of the bond.

So, for example: eth0 and eth1 in bond0 (active-backup), vmbr0 and vmbr1 uses bond0.

What is your subnet? Since the IP's you use are very close to each other. If they are in the same subnet (/24 for example), you only need 1 bridge (vmbr0) to assign to VM's. Redundacy can be reached with bonding (see above).
