The multicast forwarding-table source-nat command enables the multicast NAT function.
The undo multicast forwarding-table source-nat command disables the multicast NAT function.
multicast forwarding-table source-nat source-address [ vpn-instance vpn-instance-name ]
undo multicast forwarding-table source-nat [ vpn-instance vpn-instance-name ]
| Parameter | Description | Value |
|---|---|---|
| source-address | Specifies the source IP address of the multicast after NAT. The address is generally the address of the loopback interface of the device. | It is in dotted decimal notation. |
| vpn-instance vpn-instance-name | Specifies the name of a VPN instance. | The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
Upon receiving a multicast packet (S, G), the device translates the packet into (S', G) through NAT, and then forwards it. Meanwhile, ensure that routes to the address exist on other intranet devices. In this way, the data packets received by downstream devices can pass the RPF check and be forwarded normally.
