You cannot use the reset mld group command to clear the MLD multicast group information of static 

joins. 

The reset mld group port-info command cannot clear Layer 2 port information about MLD multicast 

groups of static joins.  

 

The reset mld group command cause an interruption of receivers’ reception of multicast data. 

 

z 

Receivers receive VOD information in the multicast mode. Receivers of different organizations 

form stub networks N1 and N2, and Host A and Host C are multicast receivers in N1 and N2 

respectively. 

z 

Switch A in the IPv6 PIM network connects to N1, and Switch B and Switch C connect to N2. 

z 

Switch A connects to N1 through VLAN-interface 100, and to other devices in the IPv6 PIM network 

through VLAN-interface 101. 

z 

Switch B and Switch C connects to N2 through their own VLAN-interface 200, and to other devices 

in the IPv6 PIM network through VLAN-interface 201 and VLAN-interface 202 respectively.
