Description

VyOS seem to suffer from iputils bug that sometimes displays 2 decimal places in ping roundrip time.

Quite likely older versions are affected as well.

$ ping 1.1

I don't seem to see the obvious problem (maybe I don't understand what you're referring to), assuming there is a problem and this is also an issue introduced by third party system components, maybe you should go upstream with feedback
