reset mld group ssm-mapping
Function
The reset mld group ssm-mapping command deletes multicast group entries established with MLD SSM mapping.
Format
reset mld group ssm-mapping all
reset mld group ssm-mapping interface interface-type interface-number { all | ipv6-group-address [ ipv6-group-mask-length ] }
Parameters
| Parameter | Description | Value |
|---|---|---|
all |
The first all deletes multicast group entries established with MLD SSM mapping on all interfaces. The second all deletes all multicast group entries established with MLD SSM mapping on a specified interface. |
- |
interface interface-type interface-number |
Deletes the multicast group entries established with MLD SSM mapping on a specified interface. |
- |
ipv6-group-address |
Specifies an IPv6 multicast group address. |
The value consists of 128 octets, which are classified into 8 groups. Each group contains 4 hexadecimal numbers in the format X:X:X:X:X:X:X:X. The value ranges from FF00:: to FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF. |
ipv6-group-mask-length |
Specifies the mask length of the multicast group address. |
The value is an integer that ranges from 8 to 128. |
Usage Guidelines
This command is valid only on the multicast groups that an interface has dynamically joined, and deletes only the MLDv1 multicast group entries within the range of SSM group addresses.
SSM mapping can be re-configured after being deleted.
After the multicast group entries established with MLD SSM mapping on an interface are deleted, the interface cannot receive multicast data. Exercise caution before running this command.
