Specifying "next-hop-self" in the general BGP router config section is 
equivalent to specifying it purely for IPv4 routes; you need to specify next-
hop-self in the IPv6 address-family section.

And you might want to disable ("no neighbor ... activate") for the
default-protocol (IPv4) as otherwise Quagga tries to advertise IPv4 over
the same session as well - which you usually wouldn't want to.
I've seen cases where both sides ran Quagga and wondered where all the
(unfiltered) IPv4-routes came from :-)
