Configuration procedure
1.
Enable IPv6 forwarding on each router and configure the IPv6 address and prefix length for each
interface according to
2.
Configure OSPFv3 on the routers in the IPv6 PIM-SSM domain to ensure network-layer reachability
among them. (Details not shown.)
3.
Enable IPv6 multicast routing, and enable IPv6 PIM-SM and MLD:
# Enable IPv6 multicast routing on Router A, and enable IPv6 PIM-SM on each interface, and run
MLDv2 on Ethernet 1/1, which connects Router A to N1.
<RouterA> system-view
[RouterA] multicast ipv6 routing-enable
[RouterA] interface ethernet 1/1
[RouterA-Ethernet1/1] mld enable
[RouterA-Ethernet1/1] mld version 2
[RouterA-Ethernet1/1] pim ipv6 sm
[RouterA-Ethernet1/1] quit
[RouterA] interface serial 2/0
[RouterA-Serial2/0] pim ipv6 sm
[RouterA-Serial2/0] quit
[RouterA] interface pos 5/0
[RouterA-Pos5/0] pim ipv6 sm
[RouterA-Pos5/0] quit
# Enable IPv6 multicast routing, and enable IPv6 PIM-SM and MLD on Router B and Router C in the
same way. (Details not shown.)
# Enable IPv6 multicast routing, and enable IPv6 PIM-SM on Router D and Router E in the same
way. (Details not shown.)
4.
Configure the IPv6 SSM group range:
# Configure the IPv6 SSM group range to be FF3E::/64 on Router A.
[RouterA] acl ipv6 number 2000
[RouterA-acl6-basic-2000] rule permit source ff3e:: 64
[RouterA-acl6-basic-2000] quit
[RouterA] pim ipv6
[RouterA-pim6] ssm-policy 2000
[RouterA-pim6] quit
# Configure the IPv6 SSM group range on Router B, Router C, Router D and Router E in the same
way. (Details not shown.)
Verifying the configuration
Use the display pim ipv6 interface command to display the IPv6 PIM information on each interface. For
example:
# Display IPv6 PIM information on Router A.
[RouterA] display pim ipv6 interface
