Displaying a list of multicast groups

Syntax: show ipv6 pim [ vrfvrf-name] interface [ ethernetslot/portnum loopbacknum venum ]

The vrf option allows you to display multicast boundary information for the VRF instance identified by the vrf-namevariable.

The ethernet port-numberparameter specifies the physical port.

The loopback num parameter specifies the loopback port.

The ve num parameter specifies a virtual interface.

The following table displays the output from the show ip pim interface ethernet command.

TABLE 27 Output from the show ipv6 pim interface ethernet command

Field	Description

Interface	Name of the interface.

Global Address	IP address of the interface.

Port	Port number of the designated router.

Mode	PIM mode.

St	State.

TTL Thr	Time to live threshold.

Multicast Boundary	Multicast boundary, if one exists.

VRF	Name of the VRF.

DR Prio	Designated router priority.

Override Interval	Override interval in milliseconds.

Displaying a list of multicast groups

To display IPv6 PIM group information, enter the show ipv6 pim group command at any CLI level.

device# show ipv6 pim group Total number of groups: 1
