Configuration procedures 
1. Configure IP addresses for interfaces: 
Enable IPv6 forwarding and configure an IP addr ess and prefix length for each interface as 
per  Figure 72 . (Details not shown.) 
2. Configure Switch A: 
# Create VLAN 101 through VLAN 104 and assign GigabitEthernet 1/0/1 through 
GigabitEthernet 1/0/4 to the four VLANs respectively.  
 system-view 
[SwitchA] vlan 101

# Create a user profile, apply policy1 to the inbound direction of GE 1/0/2 in user profile view, 
and enable the user profile.

# Create a user profile profile2 and configure the user profile so that users can join or leave only 
one IPv6 multicast group, FF1E::101. Then, enable the user profile.

Troubleshooting MLD snooping 
Layer 2 multicast forwarding cannot function 
Symptom 
Layer 2 multicast forwarding cannot function.  
Analysis 
MLD snooping is not enabled. 
Solution 
1. Use the  display current-configuration  command to display the running status of MLD snooping.  
2. If MLD snooping is not enabled, use the  mld-snooping c o m m a n d  t o  e n a b l e  M L D  s n o o p i n g  g l o b a l l y ,  
and then use  mld-snooping enable  command to enable MLD snooping in VLAN view.

1.
 
If only MLD is enabled on the switch, or if both  MLD and IPv6 PIM are enabled on the switch, the 
switch does the following: 
{  Maintains dynamic member ports or dynamic  router ports according to MLD packets  
{ Maintains dynamic router ports according to IPv6 PIM hello packets 
2. If only IPv6 PIM is enabled on  the switch, the following occurs:  
{ The switch broadcasts MLD messages as unknown messages in the VLAN.  
{ After receiving an IPv6 PIM hello message, the switch maintains the...

Configuring IPv6 PIM snooping 
Overview 
IPv6 Protocol Independent Multicast (PIM) snooping runs on Layer 2 devices. It determines which ports 
are interested in multicast data by analyzing the received IPv6 PIM messages, and adds the ports to a 
multicast forwarding entry to make sure that multic ast data can be forwarded to only the ports that are 
interested in the data.

As shown in Figure 73, Source 1 sends...

other types of received IPv6 PIM messages in the VLAN, and forwards all multicast data to all router 
ports in the VLAN. Each IPv6 PIM-capable router in the VLAN, whether interested in the multicast 
data or not, will receive all multicast data and all IPv6 PIM messages except for IPv6 PIM hello 
messages. 
•   If the Layer 2 switch runs both MLD snooping and IP v6 PIM snooping, it determines whether an IPv6 
PIM-capable router is interested in the multicast  data destined for a multicast group...

Configuration procedure 
1. Enable IPv6 forwarding, and assign IPv6 addresses: 
Enable IPv6 forwarding on the devices, configur e an IPv6 address and prefix length for each 
interface according to  Figure 74. (Details not shown.)  
2. Configure Router A: 
# Enable IPv6 multicast routing, enable IPv6 PIM-SM on each interface, and configure interface 
GigabitEthernet 1/0/2 as a C-BSR and C-RP.
