display ipv6 multicast fast-forwarding cache

Use display ipv6 multicast fast-forwarding cache to display IPv6 multicast fast forwarding entries.

Syntax

In standalone mode:

display ipv6 multicast [ vpn-instance vpn-instance-name ] fast-forwarding cache [ ipv6-source-address | ipv6-group-address ] * [ slot slot-number ]

In IRF mode:

display ipv6 multicast [ vpn-instance vpn-instance-name ] fast-forwarding cache [ ipv6-source-address | ipv6-group-address ] * [ chassis chassis-number slot slot-number ]

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays IPv6 multicast fast forwarding entries on the public network.

ipv6-source-address: Specifies an IPv6 multicast source address.

ipv6-group-address: Specifies an IPv6 multicast group address. The value range for this argument is FFxy::/16 (excluding FFx1::/16 and FFx2::/16), where "x" and "y" represent any hexadecimal numbers in the range of 0 to F.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays IPv6 multicast fast forwarding entries 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 IPv6 multicast fast forwarding entries for the global active MPU. (In IRF mode.)

Examples

# Display IPv6 multicast fast forwarding entries on the public network.

Table 101: Command output

Field	Description
Total 1 entries, 1 matched	Total number of (S, G) entries, and the total number of matching (S, G) entries.
(FE1F:60::200, FF0E::1)	(S, G) entry.
Protocol	Protocol number.
Flag	Flag for the (S, G) entry or the outgoing interface of the entry. This field displays one flag or the sum of multiple flags. In this example, the value 0x2 means that the entry has only one flag 0x2. The value 0x14 means that the outgoing interface has flags 0x10 and 0x4. The following flags are available for an entry: 0x1—The entry is created because of packets passed through between cards. 0x2—The entry is added by IPv6 multicast forwarding. The following flags are available for an outgoing interface: 0x1—The interface is added to the entry because of packets passed through between cards. 0x2—The interface is added to an existing entry. 0x4—The MAC address of the interface is needed for fast forwarding. 0x8—The interface is an outgoing interface associated with the incoming VLAN or super VLAN interface. 0x10—The interface is associated with the entry. 0x20—The interface is to be deleted.
Status	Status of the (S, G) entry or the outgoing interface: Enabled—Available. Disabled—Unavailable.
Incoming interface	Incoming interface of the (S, G) entry.
List of 1 outgoing interfaces	Outgoing interface list of the (S, G) entry.
