Comment 8 for bug 1835581

Manual validate of fix in -proposed systemd on bionic, disco and eoan (eoan expected broken until followup to systemd-242 SRU is queued).

Azure uses DHCP classless routes and their backplane security blocks all secondary IP traffic to either their IMDS service or externally bound traffic.

Attached are success logs on Azure vms, showing proper handling of secondary static IPs and dhcp IP as preferred src on default routes for Bionic and Disco (and expected failure on Eoan) for this SRU.
