Load balancer service must be installed on all clusters that are a part of Disaster Recovery (DR) to allocate Virtual IP addresses for cluster-to-cluster communications. Virtual IP addresses ensure a resilient communication between the clusters. See Installing Metallb to install Metallb. Alternatively, you can install any other load balancer service. Refer to its documentation. If you are installing in a cloud environment, ensure that you use native load balancers.
