All things related to multicast

[Tyrone Kelly <>]

Hello ALL,

I was looking for advice, perhaps a multicast cookbook, as me and my 
colleagues are tasked with enabling our Wan to support Multicast.  I 
operate a transport wan that many higher Ed institutions use for ISP 
services.  We have 3 tier one ISPs that we peer with and we're connected 
to I2 and are on transit rail.  '
Our impetus has been several request from institutions to enable 
multicast for the sake of receiving some multicast feeds like the 
Philadelphia Harmonic Symphony as well as other media.  I feel that many 
institutions may become multicast sources as well.
Challenge one is obvious setting a Multicast peering relationship up 
with another AS as well as getting multicast enabled at the instituion's 
campus level. I have been researching and modeling and ASM/SSM ANYCAST 
AUTO-RP  environment and I peer multiple RP's with MSDP.  Is this a 
consistent practice in live networks?  How does one guard against 
multiple ASM channels and receiving the wrong multicast , if possible? 
Is there a cookbook available?


THANKS
