I am using iBGP, so everything comes from the same AS. Each neighbor is
a route reflector distributing a distinct set of routes. I have tried to
add multiple-as nonetheless, but no change.

The good news is that half of the VTEP are using one next-hop and the
other half the others one. If I put down a BGP session and back, the
next hops are still distributed over the sets of VTEP. This is not
ideal, but this enough for my situation.
