multicast-nat outbound-group bind instance-group
Function
The multicast-nat outbound-group bind instance-group command is used to create relationship between outbound-group and instance-group.
The undo multicast-nat outbound-group bind instance-group command is used to delete relationship between outbound-group and instance-group.
By default, a multicast NAT outbound group is not bound to any multicast NAT instance group.
This command is supported only on the NetEngine 8000 F1A.
Format
multicast-nat outbound-group id outbound-group-id [ name outbound-group-name ] bind instance-group id instance-group-id [ name instance-group-name ] [ switch-mode clean-switch [ switch-field { first-field | second-field } ] ] [ fast-mode ]
undo multicast-nat outbound-group id outbound-group-id [ name outbound-group-name ] bind instance-group id instance-group-id [ name instance-group-name ] [ switch-mode clean-switch [ switch-field { first-field | second-field } ] ] [ fast-mode ]
undo multicast-nat outbound-group id outbound-group-id

Usage Guidelines
Usage Scenario
In multicast NAT, to translate an input multicast stream into output multicast streams, you must create a multicast NAT instance. To switch multiple input multicast streams at the same time, you must add the input and output multicast streams to a multicast NAT instance group and multicast NAT outbound group, respectively. Then run the multicast-nat outbound group bind instance group command to bind the multicast NAT outbound group to the multicast NAT instance group. To perform clean switching for the multicast NAT outbound group, you must set the switch-mode clean-switch parameter and specify a field sequence for clean switching according to the requirements of a media gateway.
Prerequisites
Output multicast streams have been added to the created multicast NAT outbound group using the assign outbound command.
Precautions
The part IDs and flow types configured for members in a multicast NAT instance group must correspond to those configured for members in a multicast NAT outbound group, and the two groups must contain members. Otherwise, the binding fails.
This command is supported only in the admin VS.Example
