Use the display pim ipv6 neighbor  command to view the IPv6 PIM neighboring relationships 
among the switches. For example:  
# Display IPv6 PIM neighboring relationships on Switch D.  
[SwitchD] display pim ipv6 neighbor

Assume that Host A needs to receive the in formation addressed to IPv6 multicast group G 
(FF0E::101). After IPv6 multicast source S (4001 ::100/64) sends IPv6 multicast packets to the 
IPv6 multicast group G, an SPT  is established through traffic flooding. Switches on the SPT path 
(Switch A and Switch D) have their (S, G) entries. Host A sends an MLD report to Switch A to join 
IPv6 multicast group G, and a (*, G) entry  is generated on Switch A. You can use the  display pim 
IPv6 routing-table  command to view the IPv6 PIM routing table information on each switch. For 
example:  
# Display IPv6 PIM multicast routing table information on Switch A.  
[SwitchA] display pim ipv6 routing-table

IPv6 PIM-SM non-scoped zone configuration example  
Network requirements 
Receivers receive VOD information through multicast. The receiver groups of different organizations form 
stub networks, and one or more receiver hosts exist in each stub network. The entire PIM domain is 
operating in the sparse mode. 
Host A and Host C are IPv6 multicast receivers in two stub networks, N1 and N2. 
VLAN-interface 105 on Switch D and VLAN-interface 102 on Switch E act as C-BSRs and C-RPs. The 
C-BSR on Switch E has a higher priority. The IPv6 multicast group range served by the C-RP is 
FF0E::101/64. Modify the hash mask length to  map a certain number of consecutive IPv6 group 
addresses within the range to the two C-RPs. 
MLDv1 runs between Switch A and N1 and between Switch B/Switch C and N2.

Configuration procedure 
1. Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing:  
Enable IPv6 forwarding on each switch and config ure the IPv6 address and prefix length for each 
interface as per  Figure 104. (Details not shown.) 
Conf

igure OSPFv3 on the switches in the IP v6 PIM-DM domain to ensure network-layer 
reachability among them. (Details not shown.)  
2.  Enable IPv6 multicast routing, and enable IPv6 PIM-SM and MLD:  
# Enable IPv6 multicast routing on Switch A, en able IPv6 PIM-SM on each interface, and enable 
MLD on VLAN-interface 300, wh ich connects Switch A to N1.

The configuration on Switch B and Switch C is similar to that on Switch A. The configuration on 
Switch D and Switch E is also similar to that on Switch A except that it is not necessary to enable 
MLD on the corresponding interfaces on these two switches.  
3. Configure a C-BSR and a C-RP: 
# On Switch D, configure the service scope of RP  advertisements, specify a C-BSR and a C-RP, and 
set the hash mask length to 128 and the priority of the C-BSR to 10.  
 system-view

[SwitchE-pim6] c-rp 1003::2 group-policy 2005 
[SwitchE-pim6] quit 
4.  Verify the configuration: 
Use the  display pim ipv6 interface  command to view the IPv6 PIM configuration and running status 
on each interface. For example:  
# Display IPv6 PIM information on all interfaces of Switch A.  
[SwitchA] display pim ipv6 interface 
 Interface            NbrCnt HelloInt   DR-Pri    DR-Address

 Vlan102              1      30         1         1003::2 
To view the BSR election information and the locally configured C-RP information in effect on a 
switch, use the  display pim ipv6 bsr-info  command. For example:  
# Display BSR information and the locally configur ed C-RP information in effect on Switch A. 
[SwitchA] display pim ipv6 bsr-info 
 Elected BSR Address: 1003::2 
     Priority: 20

Assume that Host A needs to receive information addressed to the IPv6 multicast group G 
(FF0E::100). The RP corresponding to the multicas t group G is Switch E as a result of hash 
calculation, so an RPT will be built between Switch A and Switch E. When the IPv6 multicast source 
S (4001::100/64) registers with the RP, an SPT will be built between Switch D and Switch E.  After 
receiving IPv6 multicast data, Switch A immediately  switches from the RPT to the SPT. The switches 
on the RPT path (Switch A and Switch E) have a (*, G) entry, and the switches on the SPT path 
(Switch A and Switch D) have an (S, G) entry. You can use the  display pim ipv6 routing-table 
command to view the PIM routing table information on the switches.  For example:  
# Display IPv6 PIM multicast routing table information on Switch A.  
[SwitchA] display pim ipv6 routing-table

IPv6 PIM-SM admin-scope zone configuration example 
Network requirements 
Receivers receive VOD information through multicast. The entire IPv6 PIM-SM domain is divided into IPv6 
admin-scope zone 1, IPv6 admin-scope zone 2, and  the IPv6 global zone. Switch B, Switch C, and 
Switch D are ZBRs of these three domains respectively.  
Source 1 and Source 2 send different multicast information to FF14::101. Host A receives the multicast 
i n f o r m a t i o n  o n l y  f ro m  S o u rc e  1,  a n d  H o s t  B  re c eive s  t h e  m u l t ic a s t  i n f o rm a t i o n  o n l y  f ro m  S o u rc e  2.  S o u rc e  
3 sends multicast information to multicast group FF1E::202. Host C is a multicast receiver for this 
multicast group.  
VLAN-interface 101 of Switch B acts as a C-BSR and  C-RP of admin-scope zone 1, which serves the IPv6 
multicast groups with the Scope field value in their group addresses being 4. VLAN-interface 104 of 
Switch D acts as a C-BSR and C-RP of admin-scope zone 2, which also serves the IPv6 multicast groups 
with the Scope field value in their group addresses be ing 4. VLAN-interface 109 of Switch F acts as 
C-BSRs and C-RPs of the global scope zone, which serves IPv6 multicast groups with the Scope field value 
in their group addresses being 14.  
MLDv1 runs between Switch A, Switch E, Switch I, and their respective receivers.
