Sir Pavlin,

Thank you very much for your reply. Yes, once I got my PIM SSM multicast
network works, then I'll let you know how my XORP router behaves.

Sincerely Yours,

The only SSM-specific thing you need to apply to your configuration is to
set the IGMP version to 3 (for IPv6 the MLD version has to be set to 2),
because the default version is IGMPv2 and MLDv1. E.g.

protocols {
    igmp {
        interface eth0 {
            vif eth0 {
                disable: false
                version: 3
            }
        }
        ...
    }
}

FYI, in the future IGMPv3 and MLDv2 might become the default so you won't
need the "version" statement.

The bootstrap and the static-rps configurations are optional, so you don't
need to include it. In fact, you could use SSM even if you have then
configured.

Please let us know how it goes.

Regards,
Pavlin
