Hey All,

Moving our fleet to SDN and have been testing on a new cluster but I think I'm missing something.

Are two bridges required to operate properly? Our setup is we have a bond, on the bond we have a mgmt vlan for hypervisor and mgmt vm's, and then we have a number of vlans for vmguests, pretty standard setup.

With one bridge, when I have the zone setup to use vmbr0, the other vnets show up as bond0.801.700 for example.

When I use two bridges, and set zone to use vmbr1 everything appears to work.

Here is what the interfaces looks like with two bridges and working:

Code:
auto vmbr0
iface vmbr0 inet static
        address 10.100.100.34/24
        gateway 10.100.100.1
        bridge-ports bond0.801
        bridge-stp off
        bridge-fd 0
#VL801 - Mgmt Network

auto vmbr1
iface vmbr1 inet manual
        bridge-ports bond0
        bridge-stp off
        bridge-fd 0

Also, I lose connectivity if I define vlan 801 as a vnet inside the zone, I assume since it is already defined on each host as the mgmt vlan?

Thanks for any guidance, just wondering what the best and most efficient way to do this is.
