... is there a way to specify encrypt within DC? The quick answer to your question is no. But you've got me really curious now because you have a very strange setup which makes no sense to me and I'm hoping you could elaborate. Effectively you're saying: (a) you trust the network between DC1 and DC2 so you don't encrypt intra-DC comms, (b) but you don't trust the network in DC2 so comms between nodes in DC2 are encrypted. That doesn't make sense to me. Is DC2 in some untrusted DMZ? This statement also begs the question: ... where existing dc don't have encryption between the nodes but the new > DC have encryption enabled How do you plan to bootstrap the new nodes? And if they're already bootstrapped, are you trying to join 2 separate clusters together? Because if you are, that's a very bad idea. You'll end up corrupting the schema assuming you know enough to override the cluster_name in system.local. I would strongly advise against it if that's what you're trying to achieve. Cheers!
