Re: VPNv4 next-hop-self

That's going to very much depend on how you have/are building your
LSPs. The next-hop-self in the wrong place will very definitely affect
the MPLS traffic flow through your network.

VPNv4 isn't techncially different than "regular" IPv4 routes. So your
thought process for why you'd need to or not need to do that is the
same. But presumably you've built your ISP with having reachability
to/from all PE routers' loopbacks.

Monitor your routes... Look at your next-hop information and see if
it's what you expect it to be! If it's not... Change it to something
else! Just be aware of whether it messes with your perceived traffic
engineering. :)
