[Rdo-list] Neutron with existing network issues.

Hi  I am new to RDO openstack. I have installed in one single bare metal server which had 2 NICS connected with different subnets on my company network.  1) Primary NIC subnet: 10.58.100.24 - This is where i have installed openstack and openstack dashboard is listening to logon from this IP.2) Tenant NIC subnet: 10.68.200.5 - this is a secondary IP which i kept for tenant network so that i can logon.3) 1 br-ex interface ip 10.58.100.24 I have used br-ex interface address(which is my primary 1GB NIC  IP)  configured for  tenant however i cannot ping tenant instance ip  10.68.200.25 from my management node but can ping floating IPs(10.58.100.25)  and can do SSH to floating ip. can someone provide a tip or help how to ping tenant IP as well connect to tenant IP without floating IP.  At the end i need the below.1) i need to have tenant network on 10.68.200.0/24, i need to ping this network so that tenant can logon to SSH without floating IP.2) i have requirement to have 2 Network interfaces on a instance ? how do i accomplish this ? becasue every tenant have fense network so i can only get one network when i spin instance from image ?
