The multicast ipv6 boundary command configures a multicast boundary on an interface.
The undo multicast ipv6 boundary command deletes the configured multicast boundary.
By default, no multicast boundary is configured on an interface.
multicast ipv6 boundary { ipv6-group-address ipv6-group-mask-length | scope scope-id }
undo multicast ipv6 boundary { ipv6-group-address ipv6-group-mask-length | all | scope }
| Parameter | Description | Value |
|---|---|---|
ipv6-group-address |
Specifies a multicast group address. |
The address is a 32-digit hexadecimal number, in the format X:X:X:X:X:X:X:X. An IPv6 multicast address starts with FF. |
ipv6-group-mask-length |
Specifies the mask length of an IPv6 multicast group address. |
The value is an integer that ranges from 8 to 128. |
scope scope-id |
Specifies a scope ID. |
The value is an integer that ranges from 3 to 15. |
all |
Deletes all the multicast boundaries configured on an interface. |

Usage Scenario
Data of some multicast groups needs to be forwarded within a specified range. For example, each BSR administrative domain serves a specific group address range, and data packets sent from multicast sources to these groups need to be forwarded within the matching administrative domain. After a multicast boundary is configured for specified multicast groups on an interface, multicast packets sent to these groups cannot be forwarded through the interface. This restricts multicast forwarding within a range.
Prerequisites
IPv6 multicast routing has been enabled globally using the multicast ipv6 routing-enable command in the system view.
Precautions
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 replaced by A.
