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.
