Parameters

vlan vlan-id: Displays the IPv6 PIM snooping neighbor information of the specified VLAN. The vlan-id argument is in the range of 1 to 4094. If you do not specify a VLAN, this command displays the IPv6 PIM snooping neighbor information in all VLANs.

slot slot-number: Displays the IPv6 PIM snooping neighbor information of the card specified by its slot number. If no slot is specified, the command displays the IPv6 PIM snooping neighbor information of all cards.

|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

exclude: Displays all lines that do not match the specified regular expression.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Description

Use the display pim-snooping ipv6 neighbor command to display IPv6 PIM snooping neighbor information.

Examples

# Display IPv6 PIM snooping neighbor information about VLAN 2.

<Sysname> display pim-snooping ipv6 neighbor vlan 2

Table 1 Output description

Field	Description
Total number of neighbors	Total number of IPv6 PIM snooping neighbors.
Neighbor	IP address of the IPv6 PIM snooping neighbor.
Port	Name of the port that connects to the IPv6 PIM snooping neighbor.
Expires	Remaining time before the IPv6 PIM snooping neighbor expires. Never means the IPv6 PIM snooping neighbor never expires.
Option Flags	Possible values includes the following items: ·       LAN Prune Delay—Indicates that the IPv6 PIM hello messages received from the neighbor carry the LAN_Prune_Delay option. ·       LAN Prune Delay(T)—Indicates that the IPv6 PIM hello messages received from the neighbor carry the LAN_Prune_Delay option, and the join suppression function has been enabled.

 

display pim-snooping ipv6 routing-table

Default level

1: Monitor level

Parameters

vlan vlan-id: Displays the IPv6 PIM snooping routing entries  of the specified VLAN. The vlan-id argument is in the range of 1 to 4094. If you do not specify a VLAN, this command displays the IPv6 PIM snooping routing entries  in all VLANs.

slot slot-number: Displays  the IPv6 PIM snooping routing entries  of the card specified by its slot number. If no slot is specified, the command displays information about the IPv6 PIM snooping routing entries on the main board.

|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

exclude: Displays all lines that do not match the specified regular expression.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Description

Use the display pim-snooping ipv6 routing-table command to display the IPv6 PIM snooping routing table.

Examples

# Display the IPv6 PIM snooping routing entries of VLAN 2.

<Sysname> display pim-snooping ipv6 routing-table vlan 2

  Total 1 entry(ies)

  FSM Flag: NI-no info, J-join, PP-prune pending

 

  VLAN ID: 2

    Total 1 entry(ies)

    (2000::1, FF1E::1)

      Upstream neighbor: FE80::101

        Total number of downstream ports: 2

          1: GE3/1/3

          2: GE3/1/4

      Upstream neighbor: FE80::102

        Total number of downstream ports: 1

          1: GE3/1/5

 

NOTE: ·       To determine the Upstream port field of an upstream interface that is not on the main board, you must specify the slot number of the card that the interface belongs to. ·       To determine the Expires and FSM fields of a non-aggregate interface that is not on the main board, you must specify the slot number of the card that the interface belongs to. For aggregate interfaces, the Expires and FSM fields are displayed, whether the slot number is specified or not.

 

Table 2 Output description

Field	Description
Total 1 entry(ies)	Total number of (S, G) entries and (*, G) entries in the IPv6 PIM snooping routing table.
FSM Flag: NI-no info, J-join, PP-prune pending	State machine flag of the downstream port. Possible values include: ·       NI—Initial state. ·       J—Join. ·       PP—Prune pending.
(2000::1, FF1E::1)	An (S, G) entry.
Upstream neighbor	Upstream neighbor of the (S, G) or (*, G) entry.
Upstream port	Upstream port of the (S, G) entry or (*, G) entry.
FSM	State machine of the downstream port.

Default level

2: System level

Parameters

None

Description

Use the pim-snooping ipv6 enable command to enable IPv6 PIM snooping in a VLAN.

Use the undo pim-snooping ipv6 enable command to disable IPv6 PIM snooping in a VLAN.

By default, IPv6 PIM snooping is disabled.

Before you enable IPv6 PIM snooping in a VLAN, be sure to enable MLD snooping globally and specially in the VLAN.

IPv6 PIM snooping does not work in a sub-VLAN of a multicast VLAN.

Related commands: mld-snooping enable.

Examples

# Enable MLD snooping globally, and enable MLD snooping and IPv6 PIM snooping in VLAN 2.

<Sysname> system-view

[Sysname] mld-snooping

[Sysname-mld-snooping] quit
