display multicast routing-table

Function

The display multicast routing-table command displays information about a multicast routing table.

Format

display multicast [ vpn-instance vpn-instance-name | all-instance ] routing-table [ group-address [ mask { group-mask | group-mask-length } ] | source-address [ mask { source-mask | source-mask-length } ] | incoming-interface { interface-type interface-number | register } | outgoing-interface { include | exclude | match } { interface-type interface-number | register | none } ] ^* [ outgoing-interface-number [ number ] ]

display multicast routing-table [ group-address [ mask { group-mask | group-mask-length } ] | source-address [ mask { source-mask | source-mask-length } ] | incoming-interface { interface-type interface-number | register } | outgoing-interface { include | exclude | match } { interface-type interface-number | vpn-instance vpn-instance-name | register | none } ] ^* [ outgoing-interface-number [ number ] ]

Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Specifies a VPN instance. vpn-instance-name specifies the name of the VPN instance.	The value must be an existing VPN instance name.
all-instance	Specifies all the instances.	-
group-address	Indicates the multicast group address.	The address is in dotted decimal notation. The value ranges from 224.0.1.0 to 239.255.255.255.
mask { group-mask \| group-mask-length }	Indicates the mask of the multicast group address.	group-mask: The address is in dotted decimal notation. The value ranges from 240.0.0.0 to 255.255.255.255. group-mask-length: The value is an integer that ranges from 4 to 32
source-address	Indicates the multicast source address.	The address is in dotted decimal notation.
mask { source-mask \| source-mask-length }	Indicates the mask of the specified source address.	source-mask: The address is in dotted decimal notation. The value ranges from 0.0.0.0 to 255.255.255.255. source-mask-length: The value is an integer that ranges from 0 to 32
incoming-interface	Indicates the upstream interface of a multicast routing entry.	-
interface-type interface-number	Indicates the type and the number of an interface.	-
register	Indicates the register interface of a multicast routing entry.	-
outgoing-interface	Indicates the downstream interface of a multicast routing entry.	-
include	Indicates the (S, G) entries whose downstream interface list contains specified downstream interfaces.	-
exclude	Indicates the (S, G) entries whose downstream interface list does not contain specified downstream interfaces.	-
match	Indicates (S, G) entries whose the downstream interface list contains only one interface that is the same as a specified downstream interface.	-
none	Indicates that the downstream interface list is null.	-
outgoing-interface-number	Indicates the number of downstream interfaces of multicast routing entries.	-
number	Specifies the number of downstream interfaces.	The value is an integer that ranges from 0 to 2048.

Usage Guidelines

The display multicast routing-table command is used to display the information of a multicast routing table.

Example

# Display the corresponding routing entry of a multicast group in the multicast routing table.

<HUAWEI> display multicast routing-table
Multicast routing table of VPN-Instance: public net
 Total 1 entry
 00001. (192.168.0.2, 227.0.0.1)
       Uptime: 00:00:28
       Upstream Interface: Vlanif10
       List of 2 downstream interfaces
           1:  Vlanif20
           2:  Vlanif30

**Table 1** Description of the **display multicast routing-table** command output
Item	Description
Multicast routing table of VPN-Instance	VPN instance to which the multicast routing information corresponds. public net indicates the public network instance.
Total 1 entry	Number of eligible routing entries.
00001	Sequence number of the (S, G) entry.
(192.168.0.2, 227.0.0.1)	(S, G) entry in the multicast routing table.
Uptime	Time that elapsed since the (S, G) entry was generated.
Upstream Interface	Upstream interface of the (S, G) entry.
List of 2 downstream interfaces	Downstream interface list.

# Display the number of downstream interfaces of the multicast routing entries.

<HUAWEI> display multicast routing-table outgoing-interface-number
