full mesh network for ceph configuration

[dbrega]

I am following the guide
https://pve.proxmox.com/wiki/Full_Mesh_Network_for_Ceph_Server#Broadcast_setup
In the last paragraph describing the BROADCAST SETUP configuration, I set up two network cards for each host to be used with ceph.
When I install and configure ceph, there are two fields to fill in the SETUP -> CONFIGURATION window:
- Public Network
- Cluster Network
Should I put the same bond in both, or would it be better to create two bonds, one for each setting?

Assuming it's a 3-node Ceph cluster with no switch per https://pve.proxmox.com/wiki/Full_Mesh_Network_for_Ceph_Server#Example I put the Ceph public, private, and Corosync network traffic on this network.

I also set the datacenter migration network to use this network (either via GUI or CLI) and set it to insecure (via CLI).

So, to your question, set Public & Cluster network to the full-mesh broadcast network.

P.S. To really make sure this network traffic is never routed, I use 169.254.1.0/24 (IPv4 link-local address) for this network.
