Load balance multicast stream

Hi, i have the same stream coming from 2 different

directions. The 2 routers in the multicast server are using hsrp. My question is, can i load balance the stream?The method in use is SSM.

Re: Load balance multicast stream

PIM (dense/sparse) will not load balance multicast packets due to prune behavior to prevent duplicate packets. However, GRE tunnel(s) can be used to "load balance" multicast traffic. There is also another global command "ip multicast multipath" which allows load balancing But it will only load balance If multiple sources exist for the same group(s):

Re: Load balance multicast stream

How did this work out? Did this work for you?

I am hitting the same issue and looking for a simple way to load balance SSM MC with a L3 switch if at all possible.

I am going to lab this up and give it a shot.

Thank you,

-Steve
