display multicast forwarding df-info

Use display multicast forwarding df-info to display DF information.

Syntax

In standalone mode:

display multicast [ vpn-instance vpn-instance-name ] forwarding df-info [ rp-address ] [ verbose ] [ slot slot-number ]

In IRF mode:

display multicast [ vpn-instance vpn-instance-name ] forwarding df-info [ rp-address ] [ verbose ] [ chassis chassis-number slot slot-number ]

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays DF information on the public network.

rp-address: Specifies a BIDIR-PIM RP by its IP address.

verbose: Specifies detailed information. If you do not specify this keyword, the command displays brief information about DFs.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays DF information for the MPU. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command displays DF information for the global active MPU. (In IRF mode.)

Usage guidelines

In a BIDIR-PIM domain, only the DF on each subnet can forward multicast data destined for a multicast group toward the RP of the group. For more information about the DF, see IP Multicast Configuration Guide.

Table 25: Command output

Field	Description
Total 1 RPs, 1 matched	Total number of RPs, and the total number of matching RPs.
00001	Sequence number of the entry to which the RP is designated.
RP address	IP address of the RP.
MID	ID of the entry to which the RP is designated. Each entry to which the RP is designated has a unique MID.
Flags	Entry flag. This field displays one flag or the sum of multiple flags. In this example, the value 0x0 means that the entry has only one flag 0x0. The following flags are available for an entry: 0x0—The entry is in correct state. 0x4—The entry fails to update. 0x8—DF interface information fails to update for the entry. 0x40—The entry is to be deleted. 0x100—The entry is being deleted. 0x200—The entry is in GR state.
Uptime	Length of time for which the entry has been up.
RPF interface	RPF interface to the RP.
List of 1 DF interfaces	DF interface list.
