R0106-HP MSR Router Series IP Multicast Command Reference(V7)
60
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 GigabitEthernet 2/1/1 as the forwarding boundary of multicast groups in the range of
239.2.0.0/16.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] multicast boundary 239.2.0.0 16

Use undo multicast routing to disable IP multicast routing.
Syntax
multicast routing [ vpn-instance vpn-instance-name ]
undo multicast routing [ vpn-instance vpn-instance-name ]
Default
IP multicast routing is disabled.
Views
System view
Predefined user roles
network-admin
Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string
of 1 to 31 characters. If you do not specify any VPN instance, the command enables IP multicast routing
on the public network.
Usage guidelines
You must enable IP multicast routing before you execute other Layer 3 multicast commands on the public
network or VPN instance.
The device does not forward any multicast packets before IP multicast routing is enabled.
Examples
# Enable IP multicast routing and enter MRIB view on the public network.
