Field Descri
p
tion
Output packet count on outgoing
interface
Total number of multicast packets transmitted on the outgoing interface
Total number of packets for this
source-group pair
Total number of packets from the specified source forwarded by this
router to the specified group
Protocol Multicast routing protocol in use
Forwarding TTL
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 multicast boundary to configure a multicast forwarding boundary.
Use undo multicast boundary 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
address range. If the destination address of a multicast packet matches the set boundary condition, the
packet will not be forwarded.
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 will be
removed.
Related commands: display multicast boundary.
Examples
# Configure GigabitEthernet 0/1 to be the forwarding boundary of multicast groups in the range of
239.2.0.0/16.
