Hi Sam,
Yeah somehow `lo:` is not getting skipped, probably due to those
patches. (I guess it is because the 2nd patch looks for `lo:` but in
fact the ifa_name is probably just `lo` without the colon)

I don't know why this impacts you but not us -- we already upgraded
one of our clusters to 14.2.18 on Centos 8, and ceph is choosing the
correct interface without needing any network options. And lo: is the
first interface [1] here too.
Could it be as simple as the iface names being sorted alphabetically?
Here we have ens785f0 which would come before lo, but your interface
`p2p2` would come after.
I renamed a 14.2.18 osd server's network interface to "zzzceph" (was
ceph before" and restarted the node. It does come up with the correct ip
(ms_bind_ipv4=false, ms_bind_ipv6=true). So it does not seem to be as
simple as this, or the ms_bind option migth matter here as well, dunno.
FYI,
Gr. Stefan
