[PVE-User] Are two bridges to the same network possible?

[Frank Thommen]

Hello,

(how) can I connect two virtual bridges to the same network (using the 
same gateway)?

Our currently-being-built-up PVE server has four Linux network bonds 
connecting to two three networks. One is being used for the PVE server 
itself (administration, web ui ecc), the other three for virtual 
machines which will reside in three different networks.  One of these 
three networks is the same as the one where the PVE server is residing, 
but I'd still like to use separate NICs for the VMs.

The server itself is attached to the default vmbr0 (using bond0).  But 
as soon as I want to configure a second bridge vmbr1 (using bond1) to 
the same network, PROXMOX complains that the default gateway already exists.

Is it technically possible/supported to have multiple bridges to the 
same network (with the same gateways)?

Cheers
