Upgrade 1.2.x with VRRP enabled


I have a problem which maybe better placed here on the forums. As i have stated in T459, I have got a problem regarding the changes which were made to VRRP, in particular that the line “native_ipv6” is added to the keepalived.conf in recent nightly/rolling versions.

This is a problem because older nightly builds, like 999.201701160336, don’t add that particular line in the configuration. As I need to do upgrade one router after another, this will cause my VRRP configuration to break, as both devices will try to operate as master.

Do you have any advice how I should deal with this problem? Upgrading all devices at the same time is not really an option with my setup, but maybe there is some kind of reasonable workaround which you would recommend?

Thank you very much!
