Step 2 is for cluster configuration, including for Pacemaker, HAProxy , Galera/MySQL, etc. How many controller node(s) did you have? Did you use any custom roles or composable services? If using the default controller role (i.e. monolithic), It has to be either 1 or 3 controller nodes with Tripleo.

I have only one controller.. with configuration as http://paste.openstack.org/show/729571/ also i used test-net.yaml for static ip configuration

Before we go further, first I want to make sure if you have configured the switch properly. If you have two NICs for each overcloud node, you need to set trunk ports for the NICs that carry VLAN traffics, if you choose to use network isolation.

Bear in mind that some "not-so-smart" switches require you to manually setup each VLAN ID for trunk ports. You may check with your switch manual for that.

In my case, I used NIC1 on a native vlan for undercloud control plane traffic and NIC2 for all VLANs traffics (including the external/floating IP network) on my overcloud nodes. Without knowing your network setup, the config files may not work.
