Field Descri

Forwarding TTL
The minimum TTL that a packet is required to have before it can be
forwarded over the outgoing interface
multicast boundary
Syntax
multicast boundary group-address { mask | mask-length }
undo multicast boundary { group-address { mask | mask-length } | all }
View
Interface view
Default level
2: System level
Parameters
group-address: Multicast group address, in the range of 224.0.0.0 to 239.255.255.255.
mask: Mask of the multicast group address.
mask-length: Mask length of the multicast group address, in the range of 4 to 32.
all: Specifies to remove all forwarding boundaries configured on the interface.
Description
Use the multicast boundary command to configure a multicast forwarding boundary.
Use the undo multicast boundary command to remove a multicast forwarding boundary.
By default, no multicast forwarding boundary is configured.
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.
