display multicast ipv6 routing-table

Function

The display multicast ipv6 routing-table command displays information about an IPv6 multicast routing table.

Format

display multicast ipv6 routing-table [ ipv6-source-address [ ipv6-source-mask-length ] | ipv6-group-address [ ipv6-group-mask-length ] | incoming-interface { interface-type interface-number | register } | outgoing-interface { exclude | include | match } { interface-type interface-number | register | none } ] ^* [ outgoing-interface-number [ number ] ]

Parameters

Parameter	Description	Value
ipv6-source-address	Specifies the IPv6 address of a multicast source.	The address is a 32-digit hexadecimal number, in the format X:X:X:X:X:X:X:X.
ipv6-source-mask-length	Specifies the mask length of a multicast source address.	The value is an integer that ranges from 0 to 128.
ipv6-group-address	Specifies the IPv6 address of a multicast group.	The address is a 32-digit hexadecimal number, in the format X:X:X:X:X:X:X:X. An IPv6 multicast address starts with FF.
ipv6-group-mask-length	Specifies the mask length of an IPv6 multicast group address.	The value is an integer that ranges from 8 to 128.
incoming-interface	Indicates the incoming interface of a multicast forwarding entry.	-
interface-type interface-number	Specifies the type and number of an interface.	-
register	Indicates the register interface of IPv6 PIM-SM.	-
outgoing-interface	Indicates the outgoing interface of a multicast forwarding entry.	-
include	Displays the (S, G) entries whose downstream interface list contains specified outgoing interfaces.	-
exclude	Displays the (S, G) entries whose downstream interface list does not contain specified outgoing interfaces.	-
match	Displays (S, G) entries whose the downstream interface list contains only one interface that is the same as a specified outgoing interface.	If no interface is specified, the (S, G) entry with the null downstream interface list is displayed.
none	Displays the routing entry without a downstream interface.	-
outgoing-interface-number	Displays the number of the outgoing interfaces of multicast routing entries.	-
number	Specifies the number of outgoing interfaces.	-

Usage Guidelines

You can run the display multicast ipv6 routing-table command to view the IPv6 multicast routing table, including the multicast source address, multicast group address, upstream interface, and downstream interface list.

Example

# Display the corresponding routing entry of a multicast group in the IPv6 multicast routing table.
