Example for Configuring Clean Switching of Multicast Streams in Multicast Groups
This section provides an example for configuring clean switching of multiple multicast streams in two input multicast groups.
Networking Requirements
On the network shown in Figure 1, four multicast streams are input from source 1 and source 2 to switch 1 and switch 2, respectively. Switch 1 and switch 2 aggregate the multicast streams into input multicast groups 1 and 2, respectively. Each input multicast group contains four multicast streams. After the two multicast groups enter the router, the router outputs only the four multicast streams in multicast group 1 at the beginning. Output multicast group 1 retains the characteristics of the multicast streams. If clean switching is required, the controller delivers a switching instruction to the router so that the router outputs the content of multicast group 2.
Configuration requirements: Input multicast streams 1 to 4 form input multicast group 1, and input multicast streams 5 to 8 form input multicast group 2. Before receiving a switching instruction from the controller, the router outputs the content of multicast group 1. After receiving a switching instruction from the controller, the router outputs the content of multicast group 2, ensuring that images are smooth and clear.

Configuration Roadmap
The configuration roadmap is as follows:
Enable multicast NAT globally.
Create multicast NAT instances.
Create a multicast NAT instance group and add the multicast NAT instances to the group.
Configure traffic policies.
Enable multicast stream translation on an outbound interface and configure multicast stream translation parameters.
Configure a multicast NAT outbound group and add the specified output multicast streams to the multicast NAT outbound group.
Bind the multicast NAT outbound group to the multicast NAT instance group.
Configure clean switching of multicast streams in multicast groups.
Data Preparation
To complete the configuration, you need the following data:
- Multicast NAT instance names: streamin1, streamin2, streamin3, streamin4, streamin5, streamin6, streamin7, and streamin8
- ACL names required for level-1 traffic classifiers: 4001 and 4002
- Level-1 traffic classifier names: rule_mac1 and rule_mac2
- Level-1 traffic behavior names: rule_mac1 and rule_mac2
- Level-1 traffic policy names: match1_mac_list and match2_mac_list2
- ACL names required for level-2 traffic classifiers: 3001, 3002, 3003, 3004, 3005, 3006, 3007, and 3008
- Level-2 traffic classifier names: rule_ip1, rule_ip2, rule_ip3, rule_ip4, rule_ip5, rule_ip6, rule_ip7, and rule_ip8
- Level-2 traffic behavior names: rule_ip1, rule_ip2, rule_ip3, rule_ip4, rule_ip5, rule_ip6, rule_ip7, and rule_ip8
- Level-2 traffic policy names: match1_ip_list1 and match1_ip_list2
