Hello

(Noticed while looking for some missed / forgotten e-mails)

Thanks for the bugreport. For IPv6 tables (due to ugliness of how MP-BGP
handles bgp_nexthop), we forgot to generate fake MP_REACH_NLRI attribute
with bgp_nexthop.

The resulting files worked with bgpdump (which i used for tests), just
displayed some default bgp_nexthop.

Fixed here (now it works with bgpdump, mrt2bgpdump and bgpscanner):
