You have a minor misconfiguration, but I've had trouble with the address
picking logic before, on a L3 routed ECMP BGP topography on IPv6 (using
the Cumulus magic link-local IPv6 BGP)

Keep this, but see below.

public_bind_addr is only used by mons.

There is no such option as 'cluster_bind_addr'; it's just 'cluster_addr'

Set the following in the OSD block:
| public_network = # keep empty; empty != unset
| cluster_network = # keep empty; empty != unset
| cluster_addr = 10.10.200.5
| public_addr = 10.10.200.5

Alternatively, see the code src/common/pick_address.cc to see about
using cluster_network_interface and public_network_interface.
