Thanks Phil. What about inter-domain IPv6 multicast? It's SSM, Embedded-RP, or bust? That seems rather limiting but maybe that's how it is.
Also - if you can't really have multiple PIM domains (or can't live with above restrictions) do you just use one gigantic PIMv6-Anycast domain? Is that the best practice and you rely on Anycast to keep traffic "local?" --Jim > -----Original Message----- > From: [email protected] [mailto:ipv6- > [email protected]] On Behalf Of Phil Mayers > Sent: Wednesday, June 04, 2014 2:52 PM > To: [email protected] > Subject: Re: Large IPv6 Multicast Domains > > On 04/06/2014 16:57, James Small wrote: > > > 1)There is no MSDPv6 and probably never will be.
