[j-nsp] multicast load-balance

[david.roy at orange-ftgroup.com]

Hi,

Without the join-load-balance statement, PIM uses the RPF interface to join the (S,G). In case of ECMP, Junos makes a Hash on the source address in order to select one of the links as the RPF interface. So if you have several streams with the same source address, all streams will have the same RPF interface, but if you you have several sources, your streams will be load balanced. 

Regards,
David

Experts,
do you know if Junos (8.5 for mx960) will load balance across two equal cost path once I install them in inet.2 with the following:

routing-options {
    rib inet.2 {
        static {
            route 104.104.104.104/29 next-hop 1.1.1.1;
            route 104.104.104.104/29 next-hop 2.2.2.2;
        }
    }
}

and pim is running on both interfaces?

Or I have to do something more?

Thanks,
BIT.
