3Com Switch 8800 Advanced Software V5 Configuration Guide

712 CHAPTER 47: CENTRALIZED MODE FOR IPV6
[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 VLAN 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 C is similar to the configuration on Switch B.
4 Configure a service loop group for IPv6 multicast and IPv6 unicast on Switch B and
Switch C:
[SwitchB] link-aggregation group 1 mode manual
[SwitchB] link-aggregation group 1 service-type ipv6
[SwitchB] interface gigabitethernet 2/1/1
[SwitchB-GigabitEthernet2/1/1] stp disable
[SwitchB-GigabitEthernet2/1/1] port link-aggregation group 1
[SwitchB-GigabitEthernet2/1/1] quit
[SwitchB]link-aggregation group 2 mode manual
[SwitchB]link-aggregation group 2 service-type ipv6mc
[SwitchB]interface GigabitEthernet 2/1/2
[SwitchB-GigabitEthernet2/1/2]stp disable
[SwitchB-GigabitEthernet2/1/2]port link-aggregation group 2
[SwitchB-GigabitEthernet2/1/2]q
After the configuration mentioned above, when receiving IPv6 multicast data from
Switch A, Switch B forwards the data to its IPv6-capable module, which processes
and forwards the data to the downstream device.
The configuration on Switch C is similar to the configuration on Switch B.
5 Verify the configuration
Use the display link-aggregation service-type command to view the
configuration of the service loop group.
# View the configuration of the service loop group on Switch B.
[SwitchB] display link-aggregation service-type
Service-Loop Service Quote
Group ID Type Number
---------------------------------------------------------
1 ipv6 0
2 ipv6mc 0
[SwitchB]
The above information shows that a service loop group has been correctly
established for IPv6 multicast and unicast.
The information on Switch C is similar to that on Switch B.
