This will never work - br0.99 is not a bridge but a vlan interface.

I'd also rather create ifcfg-eth0.99 vlan and put eth0.99 into br1
instead of br0.99. AFAIR, the vlan 99 id cannot be set in eth0's
hardware, because the bridge does not forward/offload it (see also
ethtool -k br0).

-> no IP setup on slaves, they're owned by the master - the IP is
set on master, that is on br1 in this case.
