Configuring PMRI

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

IP multicast boundaries

The IP multicast boundary feature is designed to selectively allow or disallow multicast flows to configured interfaces.

The ip multicast-boundarycommand 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.
