Do you need filters/policies/route-maps in a VRF? If a customer messes
up, they only take out their own VRF. OSPF in a VRF can be pretty much
hands-off. You do not even need to configure neighbors. The only problem
is if your customer sends you a million routes.

It would be great if someone came up with a zero-configuration solution
for BGP. I have seriously considered switching our default PE-CE routing
protocol to eBGP, but it ends up quite complicated.

OSPF may be expensive in theory, but in practice it performs well.
