  The Janet dbeacon shows that IPv6 multicast is working between a few 
networks.

 Just heard back from the Cisco BU via my Systems Engineer that Cisco does 
not support Embedded RP for IPv6 multicast on the Nexus 7000 and that it is 
not on Cisco’s roadmap.  They did say to "Please send a business case 
justification to see if we can get it on a roadmap”.
