Hello;

The old MBone - the set of DVMRP domains connected by tunnels, is nearly
dead - it
shows up as AS10888.
The native multicast enabled mbone is called by some the MBone, but
this usage is not universal.

At any rate, from Sri Lanka you may have trouble getting a direct
connection to
the multicast enabled Internet. I recommend Sprint in general as the
most cluefull
of the large multicast providers. I do not know where or with whom you
peer, but possible "nearby" multicast service providers include

AS 2497 Internet Inititative Japan Inc.
AS 9270         Korea Telecom   
AS 9589 UUNET Hong Kong Ltd.

I cannot speak as to their ability.

Also, Enron or Qwest might be able to help.

If you want to get up quickly, unless you directly peer with someone who
does multicast,
you will need a tunnel to someone who does. We could help you with that...

As Golding says, you will need to speak MSDP and MBGP, as well as
(strongly recommended)
PIM-SM and IGMP internally

Cisco documentation can be obtained from
ftp://ftpeng.cisco.com/ipmulticast.html and
http://www.ieng.com/warp/public/cc/techno/protocol/ipmu/tech/ipcas_dg.htm

Also, you should read the info in

http://www.live.com/mbone/  and
http://www.ietf.org/meetings/get-mbone.html

Further info is available from http://www.ipmulticast.com/ - you should
think about
joining the IP Multicast mailing list, which is more appropriate for multicast
questions than NANOG -
