Configure MLD Static Adding

Network Requirements

• The whole network runs the IPv6 PIM-SM protocol.
• Receiver is one receiver of the Device stub network.
• Run MLDv2 between Device and the stub network.
• Device interface vlan3 adds to multicast group FF1E::1 statically.

Configuration Steps

Step 1: Configure VLAN, and add the port to the corresponding VLAN (omitted).

Step 2: Configure the IPv6 address of the interface (omitted).

Step 3: Globally enable the IPv6 multicast forwarding, enable the multicast protocol IPv6 PIM-SM on the interface. Enable MLD on the interface of connecting the Receiver.

#Configure Device.

Globally enable the IPv6 multicast forwarding, enable the multicast protocol IPv6 PIM-SM on the related interfaces, and enable MLD on the interface of connecting Receiver.

#View the MLD information of Device interface vlan3.

Device#show ipv6 mld interface vlan3
Interface vlan3 (Index 23) 
 MLD Enabled, Active 
 Querier: fe80::201:2ff:fe03:406 (Self) 
 Default version: 2 
 Querier parameter:  
   Query interval is 125 seconds 
   Querier timeout is 255 seconds 
   Query response time is 10 seconds 
   Last member query response interval is 1 seconds 
   Last member query count is 2  
   Group Membership interval is 260 seconds 
   Robustness variable is 2 

Step 4: Device interface vlan3 adds to multicast group FF1E::1 statically.

#Configure Device.

Step 5: Check the result.

#Source sends the multicast packet with multicast group FF1E::1.

#View the multicast member table of Device.
