//--------------------

By above excerpt it seems like, there is a problem with DNS.

There is no firewall in between it is a plain and simple setup.  

Site A- RWDC /1.0.0.0/24   -- 2012R2 Server

Site B- RODC /192.168.0.0/24 -- 2008R2 Server

Cluster node can only reach to site B. Moment I make cluster node reachable to RWDC, it works however that doesn't serve the main purpose of the environment.

In Netmon trace as well I see the difference in DNS query used for VCO netname.

I believe for this setup we do not need pure 2012R2 DC environment.

Any help would be appreciated, If anyone able to set it up in a right way.

Followed this article.
