all-instance: Specifies all instances. 

vpn-instance vpn-instance-name: Specifies a VPN instance. A VPN instance name is a case sensitive 

string of up to 31 characters and must not contain any space. 

all: The first all specifies to clear multicast group information created based on the configured IGMP 

SSM mappings on all interfaces, while the second all specifies to clear all multicast group information 

created based on the configured IGMP SSM mappings.  

interface-type interface-number: Specifies an interface by its type and number. 

group-address: Specifies a multicast group by its IP address, in the range of 224.0.0.0 to 

239.255.255.255. 

source-address: Specifies a multicast source by its IP address. 

mask: Subnet mask of the multicast group/source address, 255.255.255.255 by default. 

mask-length: Subnet mask length of the multicast group/source address. For a multicast group address, 

this argument has an effective value range of 4 to 32; for a multicast source address, this argument has 

an effective value range of 0 to 32. For both cases, the default value is 32.
