OUTING AND ORWARDING
Use the undo multicast boundary
boundary.
By default, no multicast forwarding boundary is configured.
Note that:
A multicast forwarding boundary sets the boundary condition for the multicast
■
groups in the specified range. If the destination address of a multicast packet
matches the set boundary condition, the packet will not be forwarded.
If an interface needs to act as a forwarding boundary for multiple multicast
■
groups, just carry out this command on the interface once for each group.
Assume that Set A and Set B are both multicast forwarding boundary sets to be
■
configured, and B is a subset of A. If A has been configured on an interface, it
is not allowed to configure B on the interface; if B has been configured on the
interface before A is configured, the previously configured B will be removed.

limit: Maximum number of downstream nodes (namely, the maximum number of
outgoing interfaces) for a single route in the multicast forwarding table. The value
ranges from 0 to 128.
Use the multicast forwarding-table downstream-limit
configure the maximum number of downstream nodes for a single route in the
multicast forwarding table.
Use the
undo multicast forwarding-table downstream-limit
restore the system default.
By default, the maximum number of downstream nodes for a single route in the
multicast forwarding table is 128.
The system-allowed maximum number varies with different device models. Refer
to your specific device model.
