group (IPv6 SSM mapping view)

Function

The group command configures IPv6 static SSM mapping source/group address mappings.

The undo group command deletes the IPv6 static SSM mapping source/group address mappings.

By default, no IPv6 static SSM mapping source/group address mapping is configured.

Format

group group-ipv6-address mask-length source source-ipv6-address

undo group { group-ipv6-address mask-length | all }

undo group group-ipv6-address mask-length source source-ipv6-address

Parameters

Parameter	Description	Value
group-ipv6-address	Indicates the IPv6 address of the multicast group.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X. The value ranges from FF00::0 to FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF.
mask-length	Indicates the mask length of a multicast group.	The value is an integer, which can be 16, 32, 64, or 128.
source-ipv6-address	Specifies the IPv6 address of a multicast source.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
all	Delete all static SSM mapping source/group address mappings.	-

Usage Guidelines

Usage Scenario

When users connected to different interfaces want to watch programs multicast by different multicast sources, run the group command to configure different SSM mappings for IPv6 policies of different interfaces. After that, MLD packets received by different interfaces can be mapped to different multicast sources and users' requirements can be answered.

Example

# Configure the static SSM mapping between the multicast source 1::1 and the multicast group FF33::1/32 for the MLD SSM mapping policy ssmmap1.

<HUAWEI> system-view
[~HUAWEI] ssm-mapping ipv6 policy ssmmap1
[*HUAWEI-ssm-map6-ssmmap1] group ff33::1 32 source 1::1
