Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Displays information about an IGMP proxy routing table in a specific VPN instance. If you specify neither vpn-instance nor all-instance in this command, the command displays only the IGMP proxy routing table in the public network instance.	The value must be an existing VPN instance name.
all-instance	Displays information about IGMP proxy routing tables in all VPN instances.	-
group-address	Displays information about the routing entry of a specified group.	The value ranges from 224.0.1.0 to 239.255.255.255, in dotted decimal notation.
mask	Indicates the mask of a multicast group address or a source address.	-
group-mask-length	Specifies the mask length of a multicast group address.	The value is an integer that ranges from 4 to 32.
group-mask	Specifies the mask of a multicast group address.	The value is in dotted decimal notation.
source-address	Displays the routing entry for a multicast source.	The value is in dotted decimal notation.
source-mask-length	Specifies the mask length of a multicast source address.	The value is an integer that ranges from 0 to 32.
source-mask	Specifies the mask of a multicast source address.	The value is in dotted decimal notation.
outgoing-interface	Displays the routing entries with a specific interface as the outbound interface.	-
include	Displays the routing entries of which the downstream interface list has a specific interface.	-
exclude	Displays the routing entries of which the downstream interface list does not have a specific interface.	-
match	Displays the routing entries of which the downstream interface list has only a specific interface.	-
interface-type interface-number	Specifies the type and number of an interface.	-
none	Displays the routing entries with an empty downstream interface list.	-
incoming-interface	Displays the routing entries with a specific interface as the inbound interface.	-
flags flag-value	Indicates an IGMP proxy routing entry with a specific type. flag-value specifies the flag of a routing entry. If you specify flags flag-value in this command, the command displays IGMP proxy routing entries with the flag.	flag-value can be act, del, join, none, niif, sgjoin, wcjoin, upchg, or wc. For information about each value, see the flag-value field description in the display pim routing-table command output.
fsm	Displays detailed information about a finite state machine (FSM).	-
outgoing-interface-number	Displays the number of downstream interfaces in an IGMP proxy routing entry.	-
number	Specifies the number of downstream interfaces in an entry to be queried.	The value is an integer that ranges from 0 to 2048.

Usage Guidelines

To find information about an IGMP proxy routing table, run the display igmp proxy routing-table command. You can specify different parameters in this command to view specific routing information. This command helps you find specific routes and locate faults.

**Table 1** Description of the **display igmp proxy routing-table fsm** command output
Item	Description
Routing table	-
Total 1 (*, G) entry; 1 (S, G) entry	Total number of (*, G) and (S, G) entries in the IGMP proxy routing table.
(*, 225.1.1.1)	(*, G) or (S, G) entry in the IGMP proxy routing table.
Flag	Flag of a (*, G) or an (S, G) entry in the IGMP proxy routing table.
UpTime	Amount of time since a (*, G) or an (S, G) entry is created.
Upstream interface	Upstream interface of a (*, G) or an (S, G) entry.
Downstream interface(s) information	Information about downstream interfaces.
Total number of downstreams	Total number of downstream interfaces.
Vlanif200	Name of a downstream interface.
Protocol	Protocol of a downstream interface.
UpTime	Amount of time a downstream interface has been in Up state, expressed in hh:mm:ss format. The time format is as follows: If the time is shorter than or equal to 24 hours, the format is hours:minutes:seconds. If the time is longer than 24 hours but shorter than or equal to one week, the format is days:hours. If the time is longer than one week, the format is weeks:days.
IGMP querier	Address of an IGMP querier
IGMP state	IGMP status on a downstream interface: NI: indicates that an (S, G) entry inherits the downstream interfaces of a (*, G) entry. BLOCK: indicates that the interface does not forward traffic based on an (S, G) entry. INCLUDE: indicates that the interface needs to join the specified group and source. EXCLUDE: indicates that the interface does not join the specified group and source.
FSM information for non-downstream interfaces	Interfaces that do not forward multicast data packets matching (*, G) or (S, G) entries.
