I have configured it as follow :

ceph_rbd_mirror_configure: true
ceph_rbd_mirror_mode: "pool"
ceph_rbd_mirror_pool: "images"
ceph_rbd_mirror_remote_cluster: "prod"
ceph_rbd_mirror_remote_user: "admin"
ceph_rbd_mirror_remote_key: "AQDGVctluyvAHRAAtjeIB3ZZ75L8yT/erZD7eg=="
ceph_rbd_mirror_remote_mon_hosts: "mon-ip:3300"

This the configs of rbdmirrors.yml
