Why do you say that. I don't see any problem with what the doc says:

# Management Network
auto eth0
    iface eth0 inet static
    address 192.168.0.2
    netmask 255.255.255.0
    gateway 192.168.0.254
    dns-nameservers 8.8.8.8

# Data Network
    auto eth1
    iface eth1 inet static
    address 10.10.10.1
    netmask 255.255.255.0

# Public Bridge
    auto eth2
    iface eth2 inet manual
    up ifconfig $IFACE 0.0.0.0 up
    up ip link set $IFACE promisc on
    down ifconfig $IFACE down
