Usage Scenario
If the incoming traffic from the upstream distributed multicast VPN is too heavy, the downstream device may be congested or a great number of packets are directly discarded. To prevent this situation, you can configure traffic shaping on the MTunnel interface of the distributed multicast VPN on the upstream router to limit the traffic rate and burst size of a connection from the desired network. In this manner, packets can be transmitted at a rather even speed rate.
Configuration Impact
This command is circular in nature. That is, the latest traffic shaping configuration overrides the previous ones.
To configure traffic shaping on the MTunnel interface in a distributed multicast VPN, you need to enable simple traffic classification on the interface, which corresponds to the MTunnel interface, at the side of the public network; otherwise, traffic will be transiently interrupted intermittently.
