Parameters
group-address: Specifies a multicast group address in the range of 224.0.0.0 to 239.255.255.255.
mask-length: Specifies the address mask length in the range of 4 to 32.
mask: Specifies the address mask.
all: Specifies all forwarding boundaries configured on the interface.
Usage guidelines
A multicast forwarding boundary sets the boundary condition for the multicast groups in the specified
address range. If the destination address of a multicast packet matches the set boundary condition, the
packet is not forwarded.
You do not need to enable IP multicast routing before executing this command.
An interface can act as a forwarding boundary for multiple multicast groups in different address ranges.
To achieve this, use this command on the interface for each multicast address range.
Assume that Set A and Set B are multicast forwarding boundary sets with different address ranges, and
B is a subset of A. If B is configured after A, A still takes effect. If A is configured after B, B is removed.
Examples
# Configure VLAN-interface 100 as the forwarding boundary of multicast groups in the range of
239.2.0.0/16.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] multicast boundary 239.2.0.0 16
