Re: ipv6 multicast testing

ok ipv6 ssm, sort of out of my scope, but the doccd says this about it:

"MLD version 2 is required for SSM to operate. MLD allows the host to
provide source information. Before SSM will run with MLD, SSM must be
supported in the Cisco IOS IPv6 router, the host where the application is
running, and the application itself."

so now i am trying to figure out how to determine and then turn on MLDv2?

and for a test what happens if you just use pim-sm and use "regular" ipv6
multicast does it work? meaning this is a SSM specific issue?
