Configuring IPv6 PIM-SSM
IMPORTANT:
The IPv6 PIM-SSM model needs the support of MLDv2. Be sure to enable MLDv2 on IPv6 PIM routers with
receivers attached to them.
IPv6 PIM-SSM configuration task list
Task Remarks
Enabling IPv6 PIM-SM Required.
Configuring the IPv6 SSM group range Optional.
Configuring IPv6 PIM common features Optional.
Configuration prerequisites
Before you configure IPv6 PIM-SSM, complete the following tasks:
• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain are interoperable at the network layer.
• Determine the IPv6 SSM group range.
Enabling IPv6 PIM-SM
The SSM model is implemented based on some subsets of IPv6 PIM-SM. Therefore, you must enable IPv6
PIM-SM before configuring IPv6 PIM-SSM.
When you deploy an IPv6 PIM-SSM domain, enable IPv6 PIM-SM on all non-border interfaces of routers.
To enable IPv6 PIM-SSM:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable IPv6 multicast routing. multicast ipv6 routing-enable Disable by default.
3. Enter interface view.
interface interface-type
interface-number
N/A
4. Enable IPv6 PIM-SM. pim ipv6 sm Disabled by default.
IMPORTANT:
All the interfaces of the same device must operate in the same IPv6 PIM mode.
