2. Configure OSPFv3 on the switches in the IPv6 PIM-SSM domain to make sure the following
conditions are met: (Details not shown.)
{
The switches are interoperable at the network layer.
{
The switches can dynamically update their routing information.
3. Enable IPv6 multicast routing, MLD, and IPv6 PIM-SM:
# On Switch A, enable IPv6 multicast routing globally.
system-view
[SwitchA] ipv6 multicast routing
[SwitchA-mrib6] quit
# Enable MLDv2 on VLAN-interface 100 (the interface that connects to the stub network).
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] mld enable
[SwitchA-Vlan-interface100] mld version 2
[SwitchA-Vlan-interface100] quit
# Enable IPv6 PIM-SM on the other interfaces.
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] ipv6 pim sm
[SwitchA-Vlan-interface101] quit
[SwitchA] interface vlan-interface 102
[SwitchA-Vlan-interface102] ipv6 pim sm
[SwitchA-Vlan-interface102] quit
# Enable IPv6 multicast routing, MLD, and IPv6 PIM-SM on Switch B and Switch C in the same way
Switch A is configured. (Details not shown.)
# Enable IPv6 multicast routing and IPv6 PIM-SM on Switch D and Switch E in the same way Switch
A is configured. (Details not shown.)
4. Configure the IPv6 SSM group range to be FF3E::/64 on Switch A.
[SwitchA] acl ipv6 number 2000
[SwitchA-acl6-basic-2000] rule permit source ff3e:: 64
[SwitchA-acl6-basic-2000] quit
[SwitchA] ipv6 pim
[SwitchA-pim6] ssm-policy 2000
[SwitchA-pim6] quit
5. Configure the IPv6 SSM group range on Switch B, Switch C, Switch D, and Switch E in the same
way Switch B is configured. (Details not shown.)
Verifying the configuration
# Display IPv6 PIM information on Switch A.
[SwitchA] display ipv6 pim interface

Assume that Host A needs to receive the information a specific IPv6 multicast source S (4001::100/64)
sends to IPv6 multicast group G (FF3E::101). Switch A builds an SPT toward the IPv6 multicast source.
Switches on the SPT path (Switch A and Switch D) have generated an (S, G) entry, but Switch E, which
