I'm trying to create a multi DC Cassandra setup on a Cloud Vendor. I have cassandra deployed in two different DC's and I want to connect them to form a single Cluster. All the deployments are done via Kubernetes. But whenever I do nodetool status, I am able to see the nodes only of that DC. Somehow the seeds from other DC's are not being connected.

Can you please guide me what is wrong or point me to an article.
