[c-nsp] huge amount of mcast traffic

Dear experts, I’ve a multicast financial market connected to my infrastructure, I’ve been informed that a new data multicast flow could reach up to 6 Gbs, so an huge amount of traffic needs to be replicated. Market is connected to an ASR 1001, than to a C6807-XL and customers are connected to

Re: [c-nsp] huge amount of mcast traffic
