Configuring PMRI
PMRI is enabled by default. To disable PMRI, enter commands such as the following.
device(config)# router pim
device(config-pim-router)# hardware-drop-disable
Syntax: [no] hardware-drop-disable
Displaying hardware-drop
Use the show ip pim sparse command to display if the hardware-drop feature has been enabled or
disabled.
device(config)#show ip pim sparse

IP multicast boundaries
The IP multicast boundary feature is designed to selectively allow or disallow multicast flows to
configured interfaces.
The ip multicast-boundary command allows you to configure a boundary on a PIM enabled interface
by defining which multicast groups may not forward packets over a specified interface. This includes
incoming and outgoing packets. By default, all interfaces that are enabled for multicast are eligible to
participate in a multicast flow provided they meet the multicast routing protocol’s criteria for participating
in a flow.
Configuration considerations
• Only one ACL can be bound to any interface.
• Normal ACL restrictions apply as to how many software ACLs can be created, but there is no
hardware restrictions on ACLs with this feature.
• Creation of a static IGMP client is allowed for a group on a port that may be prevented from
participation in the group on account of an ACL bound to the port’s interface. In such a situation,
the ACL would prevail and the port will not be added to the relevant entries.
• Either standard or extended ACLs can be used with the multicast boundary feature. When a
standard ACL is used, the address specified is treated as a group address and NOT a source
address.
