Hi
the multicast is working fine with Olive but in Qemu ( or GNS3 ) not with VMware , you will be able to see the PIM neighbors , RP elections ( auto-rp and Boot strap ) , MSDP and anycast-rp ,, if you are using sparse mode you have to generate the Multicasts traffic from the RP it self since it will not support the De / encapsulation of the register messages
if you use dense mode nothing else spacial
