9.6.3 Setting the Maximum Number of Downstream Nodes of
Multicast Forwarding Entry
A multicast device replicates a copy of multicast packets for each downstream interface. Then,
you can set the number of downstream interfaces of a single forwarding entry and adjust the
number of downstream interfaces according to the actual networking and service performance
to release the burden on the multicast device.
Context
CAUTION
This configuration becomes valid only after the reset multicast forwarding-table command is
used. Multicast services are interrupted after you run the reset multicast forwarding-table
command. So, confirm the action before you use the command.
Configurations related to the VPN instance are applicable only to the PE switch. When
configuring the maximum number of downstream nodes for a forwarding entry in a VPN instance
on a PE, perform the configuration in the VPN instance. In other cases, the maximum number
of entries in the forwarding table is configured in the public network instance.
Do as follows on the multicast switch:
Procedure
l Public network instance
1. Run:
system-view
The system view is displayed.
2. Run:
multicast forwarding-table downstream-limit limit
The maximum number of downstream nodes of a forwarding entry in the multicast
forwarding table is configured.
The maximum number is valid when it is smaller than the default value.
