I have permitted the prefix into and out of Sprint filters, FYI. I am seeing
the announcement currently through the following AS-paths.

sl-bb1-6bone#sho ipv bgp 2010::/16
BGP routing table entry for 2010::0/16, version 345
Paths: (5 availiable, best #1)
  nexthop: 3FFE:2900:A:3::2 from: 3FFE:2900:A:3::2
    linklocal: FE80::26F5:4C36 Tunnel10
    weight 0
    AS path: 7081
  nexthop: 3FFE:2900:B:F::2 from: 3FFE:2900:B:F::2
    linklocal: FE80::C5C:69A8:B Tunnel45
    weight 0
    AS path: 5761
  nexthop: 3FFE:900:0:1C::1 from: 3FFE:900:0:1C::1
    linklocal: FE80::C8E:50C2:22 Tunnel21
    weight 0
    AS path: 1225 237 7081
  nexthop: 3FFE:C00:E:1::1 from: 3FFE:C00:E:1::1
    linklocal: FE80::60:3E11:6770:27 Tunnel50
    weight 0
    AS path: 109 237 7081
  nexthop: 3FFE:2900:1::1E from: 3FFE:2900:1::1E
    linklocal: FE80::200:81FF:FED5:805A Tunnel1
    weight 0
    AS path: 561 237 7081


Should it be deemed that the 2010::/16 block will be split up into
sub-delegations, I will allow up to /24 announcements. Currently, I only
allow the /16 through.
