The multicast boundary command configures the multicast forwarding boundary for a single administrative range.
The undo multicast-boundary command deletes the configured multicast forwarding boundary.
By default, no multicast forwarding boundary is configured on an interface.
multicast boundary group-address { mask | mask-length }
undo multicast boundary { group-address { mask | mask-length } | all }
| Parameter | Description | Value |
|---|---|---|
group-address |
Specifies the address of a multicast group, used to specify a multicast group and configure the forwarding range of the multicast packets for the corresponding group. |
The address is in dotted decimal notation and ranges from 224.0.0.0 to 239.255.255.255. |
mask |
Indicates the mask of a specified group address. |
The mask is in dotted decimal notation. |
mask-length |
Indicates the mask length of a specified group address. |
The value is an integer that ranges from 4 to 32. |
all |
Deletes all the multicast forwarding boundaries configured on an interface. |

Use the multicast boundary command to configure the multicast forwarding boundary to set the forwarding range for multicast packets.
To configure the boundary for different multicast groups, you can repeat the command on the same interface.
A and B are the forwarding boundary sets of the multicast group range to be configured, and B is a subset of A. If A is first configured on an interface, B cannot be configured. If you configure A on the interface that has been configured with B, B is substituted by A.
You must run the multicast routing-enable command to enable the multicast function before using the command.
