R3303-HP HSR6800 Routers IP Multicast Command Reference

55
An interface can act as a forwarding boundary for multiple multicast groups in different address ranges.
To achieve this, execute 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

multicast forwarding-table downstream-limit
Use multicast forwarding-table downstream-limit to configure the maximum number of downstream
nodes for a single entry in the multicast forwarding table.
Use undo multicast forwarding-table downstream-limit to restore the default.
Syntax
multicast forwarding-table downstream-limit limit
undo multicast forwarding-table downstream-limit
Default
The maximum number of downstream nodes for a single multicast forwarding entry is 128.
Views
System view, VPN instance view
Default command level
2: System level
Parameters
limit: Specifies the maximum number of downstream nodes (maximum number of outgoing interfaces) for
a single multicast forwarding entry. The value range for this argument is 0 to 128.
Usage guidelines
The system-allowed maximum number varies with different device models.
Examples
# Set the maximum number of downstream nodes for a single multicast forwarding entry on the public
network to 120.
<Sysname> system-view
[Sysname] multicast forwarding-table downstream-limit 120
# Set the maximum number of downstream nodes for a single multicast forwarding entry in VPN instance
mvpn to 60.
<Sysname> system-view
[Sysname] ip vpn-instance mvpn
