With mTLS, each replication peer authenticates the other peer, and all traffic between the peers gets encrypted. mTLS encryption requires that an mTLS certificate installed on each of the peer clusters and that each peer has secure mode enabled. Contact your cluster administrator for assistance with configuring mTLS for replication.
