3Com Switch 8800 Advanced Software V5 Configuration Guide

IPv6 PIM Configuration Examples 699
[SwitchA-Vlan-interface101] quit
[SwitchA] interface vlan-interface 102
[SwitchA-Vlan-interface102] pim ipv6 dm
[SwitchA-Vlan-interface102] quit
The configuration on Switch B and Switch C is similar to the configuration on
Switch A.
3 Enable MLD on the host-side interfaces of Switch B and Switch C
# Enable IPv6 multicast routing on Switch B, and enable MLDv1 on VLAN-interface
200.
<SwitchB> system-view
[SwitchB] multicast ipv6 routing-enable
[SwitchB] interface vlan-interface 200
[SwitchB-Vlan-interface200] mld enable
[SwitchB-Vlan-interface200] quit
The configuration on Switch is similar to the configuration on Switch B.
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:
# View the IPv6 PIM configuration information on Switch A.
[SwitchA] display pim ipv6 interface
Vpn-instance: public net
Interface NbrCnt HelloInt DR-Pri DR-Address
Vlan-interface100 0 30 1 FE80::200:AFF:F

(local)
Vlan-interface102 1 30 1 FE80::A01:109:2
(local)
Use the display pim ipv6 neighbor command to view the IPv6 PIM neighboring
relationships among the switches. For example:
# View the IPv6 PIM neighboring relationships on Switch A.
[SwitchA] display pim ipv6 neighbor
Vpn-instance: public net
Total Number of Neighbors = 2

Assume that Host A needs to receive the information addressed to an IPv6
multicast group G (FF0E::101:101). After IPv6 multicast source S (2001::5) sends
IPv6 multicast packets to the IPv6 multicast group G, an SPT is established through
traffic flooding. Upon receiving the (*, G) join message from Host A, Switch B
updates its (S, G) routing entry. Then, all the IPv6 PIM switches in the SPT update
their respective (S,G) entries. You can use the display pim IPv6 routing-table
