Hi @bastelfreak. If you want me to update the README.md I assume you are looking for an example with a mixed ipv4/ipv6 instance configuration in a sync group, in a new section?

For the test I would need some guidance. Please let me know if my last commit 2780bf9 would be sufficient.

Hi. the test looks fine. It's helpful when a parameter is documented in the readme. A working example is even better.

Ok. I will look into a README example.

Travis does not seem to agree with the test being ok. Any idea what might be wrong?

Adding the config option global_tracking to sync_groups. This allows health checks for vrrp instances to continue working when they are added to a sync_group, which is needed when having VI for both ipv4 and ipv6 addresses.
