The 'post-up ip addr del 127.0.0.1/8 dev lo' was thought to be required when the loopback interface subnet mask was narrowed from /8 to /16. After testing first reboot, subsequent reboots, config reloads, and systemctl restart networking on linecards and supevisors (DNX VOQ chassis), this cleanup command does not appear to be required. As such, this change removes it as well as reverts sonic-net#15080.

Had an offline discussion with @saiarcot895. This PR doesn't solve the problem he was originally chasing with respect to uninterrupted connectivity to 127.0.0.1. #15080 is the right solution. Closing this PR. |
