the routing table on a CEPH/PVE node is:

$ ip route
default via 192.168.64.1 dev vmbr0 proto kernel onlink
192.168.64.0/20 dev vmbr0 proto kernel scope link src 192.168.70.30
192.168.254.0/24 dev vmbr2 proto kernel scope link src 192.168.254.1
192.168.255.0/24 dev vmbr1 proto kernel scope link src 192.168.255.1

vmbr2 is the CEPH network, vmbr1 is the PVE network and vmbr0 is the LAN 
network. So you suggest me to add first the 3 ceph monitors using the 
CEPH IPs network and then destroy the 3 monitors having LAN IPs?

Similarly for the ceph managers?
