Of course you have SSM and Embedded RP but that doesn’t cover all cases. For example – if you have a partnership with another organization and only want to share select multicast groups/sources then in IPv4 you use MSDP and MSDP filters. However, I don’t see how to do this with IPv6 multicast.<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='mso-list:Ignore'>2)<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Often I see different multicast domains with MSDP between them (including filters).
