deploying a DBSystem in another network then BM ODA

We are running an ODA-X10 HA on pubnet 10.10.90.10 and 10.10.90.11. Gateway is 10.10.90.80. DNS in this network is 10.10.90.90.

We want to deploy a DBSystem which uses a different network. The BM ODA should not be able to contact the DBSystem's network due to strict network separation.

We added a vnet like:

odacli create-vnetwork —name dbsys-vnet —bridge dbsys-net-br —type bridged-vlan —uniform —vlan-id 123 —interface btbond4

btbond4 is the BM ODA's public network NIC.

The system creates a btbond4.123 and a dbsys-net-br network device on BM.

The DBSystem should have the following IPs: 10.10.50.10 and 10.10.50.11, Gateway is 10.10.50.80 and DNS is 10.10.150.90.

Due to this constellation, in normal life, we would add a route to connect to the DNS. But this is not possible before the DBSystem is actually running.
