Configuration procedure
1) Enable IPv6 forwarding and configure IPv6 addresses and IPv6 unicast routing
Enable IPv6 forwarding on each switch and configure the IPv6 address and prefix length for each
interface as per Figure
Configure OSPFv3 for interoperation among the switches in the IPv6 PIM-SM domain. Ensure the
network-layer interoperation in the IPv6 PIM-DM domain and enable dynamic update of routing
information among the switches through an IPv6 unicast routing protocol. Detailed configuration steps
are omitted here.
2) Enable IPv6 multicast routing, and enable IPv6 PIM-SM and MLD
# Enable IPv6 multicast routing on Switch A, enable IPv6 PIM-SM on each interface, and enable MLD
on VLAN-interface 100, which connects Switch A to N1.
<SwitchA> system-view
[SwitchA] multicast ipv6 routing-enable
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] mld enable
[SwitchA-Vlan-interface100] pim ipv6 sm
[SwitchA-Vlan-interface100] quit
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] pim ipv6 sm
[SwitchA-Vlan-interface101] quit
[SwitchA] interface vlan-interface 102
[SwitchA-Vlan-interface102] pim ipv6 sm
[SwitchA-Vlan-interface102] quit
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.
