Example for Configuring Clean Switching of Multicast Streams
This section provides an example for configuring clean switching for two input multicast streams.
Networking Requirements
On the network shown in Figure 1, multicast streams 1 and 2 are input from sources 1 and 2 to Device B, respectively. Device B outputs only multicast stream 1, and the characteristics of multicast stream 1 remain unchanged. If clean switching is required, the controller delivers a clean switching instruction to Device B so that Device B outputs multicast stream 2. The characteristics of multicast stream 2 remain unchanged.

Configuration Roadmap
The configuration roadmap is as follows:
Enable multicast NAT globally.
Create multicast NAT instances.
Configure traffic policies.
Apply the level-1 traffic policies on the inbound interfaces of multicast streams.
Configure multicast NAT on the outbound interface of multicast streams.
Bind output multicast streams to multicast NAT instances.
Configure clean switching of multicast streams.
Data Preparation
- Multicast NAT instance names: stream1 and stream2
- 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_list
- ACL names required for level-2 traffic classifiers: 3001 and 3002
- Level-2 traffic classifier names: rule_ip1 and rule_ip2
- Level-2 traffic behavior names: rule_ip1 and rule_ip2
- Level-2 traffic policy names: match1_ip_list1 and match1_ip_list2
Procedure
- Enable multicast NAT on the device.
<HUAWEI> system-view [~HUAWEI] multicast-nat enable
- Create multicast NAT instances named stream1 and stream2 on the device.
[~HUAWEI] multicast-nat instance id 1 name stream1 [~HUAWEI] multicast-nat instance id 2 name stream2 [*HUAWEI-multicast-nat-instance-1] commit [~HUAWEI-multicast-nat-instance-1] quit
- Configure two-level traffic policies for implementing multicast NAT on the device.
- Apply the level-1 traffic policies on the inbound interfaces of multicast streams.

- Configure clean switching to switch output multicast stream 1 to output multicast stream 2.
