NOTE:
The following points apply to the hash mask length and C-BSR priority:
• You can configure these parameters at global configuration level and admin-scope zone level.
• The value configured at the admin-scope zone level have preference over the global values.
• If you do not configure these parameters at the admin-scope zone level, the corresponding global
values will be used.
For configuration of global C-BSR parameters, see “Configuring global C-BSR parameters.”
Configuring IPv6 PIM-SSM
NOTE:
The IPv6 PIM-SSM model needs the support of MLDv2. Therefore, be sure to enable MLDv2 on IPv6 PIM
routers with receivers attached to them.
IPv6 PIM-SSM configuration task list
Complete these tasks to configure IPv6 PIM-SSM:
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 any 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, a router is IPv6 PIM-
SSM capable after you enable IPv6 PIM-SM on it.
When you deploy an IPv6 PIM-SM domain, enable IPv6 PIM-SM on all non-border interfaces of routers.
Follow these steps to enable IPv6 PIM-SSM:
