[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 the IPv6 SSM group range
# 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] pim ipv6
[SwitchA-pim6] ssm-policy 2000
[SwitchA-pim6] quit
The configuration on Switch B, Switch C, Switch D, and Switch E is similar to that on Switch A.
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

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, while Switch E,
which is not on the SPT path, does not have IPv6 multicast routing entries. You can use the display pim
ipv6 routing-table command to view the IPv6 PIM routing table information on each switch. For
example:
# View the IPv6 PIM multicast routing table information on Switch A.
[SwitchA] display pim ipv6 routing-table
Total 0 (*, G) entry; 1 (S, G) entry
