updated BAY record

[Dimitry Haskin]

Hi,

I've updated the Bay's registry record with new tunnels:
   tunnel:		192.32.29.62 130.88.12.119 UMAN, UK, RIPng
   tunnel:		192.32.29.62 192.87.106.15 SURFnet, Netherlands, RIPng
   tunnel:		192.32.29.62 204.148.62.66 ANS, USA, RIPng


We've also started route filtering. In the most cases when a number of more
specific routes are advertised to us along with an aggregate, more
specific routes are ignored.  Let's know if there is any problem.

Example before filtering:

                 Prefix                      Protocol  Intf.     Metric
------------------------------------------- ---------- ------- ----------
5F00:3100::0000/32                          RIPv6      20          2
5F00:3100::0000/32                          RIPv6      12          2
5F00:3100::0000/32                          RIPv6      4           3
5F00:3100:8106:3300::0000/80                RIPv6      12          2
5F00:3100:8106:3E00::0000/80                RIPv6      4           4
5F00:3100:8106:E000::0000/80                RIPv6      4           4
5F00:3100:8106:E100::0000/80                RIPv6      4           4

After filtering

                 Prefix                      Protocol  Intf.     Metric
------------------------------------------- ---------- ------- ----------
5F00:3100::0000/32                          RIPv6      20          2
5F00:3100::0000/32                          RIPv6      12          2
5F00:3100::0000/32                          RIPv6      4           3


Thanks,
