Thanks for responding.
That part I understand and have that working right. The issue I am having is configuring
RDO Manager/Ironic to work.
In the undercloud.conf file, you specify the local interface. This seems to be used for
both PXE boot and IPMI operations. When the undercloud is installed, the networking is
not being configured correctly. If the tagged interface isn't set up correctly, I
lose access to the AMM and subsequently the IMM of the individual blade.
The local_interface is the one used for PXE booting. After undercloud
installation you should see the br-ctlplane bridge created, containing
the local_interface and the local_ip set on top of the bridge.
Regarding the IPMI operations - you should see which interface is used
for reaching the IPMI address by checking the routing table ( ip r get
$IPMI_ADDRESS).
If you're using the PXE nic for reaching the IPMI network via tagged
frames then you could try the following workaround after undercloud
installation: add a tagged ovs port to the br-ctlplane bridge with the
right vlan tag and then assign it an IP address:
ovs-vsctl add-port br-ctlplane vlanX tag=X -- set interface vlanX type=internal
ip link set dev vlanX up
ip addr add x.x.x.x/x dev vlanX
If I could get Ironic to not perform the IPMI operations and I have
to reboot manually, that would be fine but I don't seem to see how to do that in the
documentation.

Hi,
If I understand it correctly you could set up the undercloud 1G port as trunk, use
untagged frames for management and tagged for the Chassis Internal Network VLAN.
Here are some instructions to set up a vlan tagged interface:

Thanks
