Russia as a polity is very confused on this. Officially, it's civic nationalist - you're supposed to think of yourself as a part of the "Russian nation" regardless of your ethnicity, but it's also defined broadly to allow for incomplete assimilation.
As a side note, it's more difficult to talk about this in (most) languages other than Russian because they don't have the distinction that Russian itself does. The word "русский" ("russky") usually means Russian in an ethnic sense, while the word "российский" ("rossiyskiy" - from the name of the country, which is Rossiya in Russian) means Russian in a sense of pertaining or belonging to the country. Thus you can compare and contrast "russky nationalism" (ethnic) and "rossiyskiy nationalism" (civic).
In practice, the government tolerates and sometimes encourages ethnic Russian nationalism so long as it does not manifest as open political opposition.
