To do...
Enter interface view
Enable IPv6 PIM-SM
CAUTION:
All interfaces of the same device must work in the same IPv6 PIM mode.
NOTE:
For more information about the multicast ipv6 routing-enable command, see the
Command Reference
Configuring the IPv6 SSM group range
Whether the information from an IPv6 multicast source is delivered to the receivers based on the IPv6
PIM-SSM model or the IPv6 PIM-SM model depends on whether the group address in the (S, G) channel
subscribed by the receivers falls into the IPv6 SSM group range. All IPv6 PIM-SM-enabled interfaces
assume that IPv6 multicast groups within this address range are using the IPv6 SSM model.
Perform the following configuration on all routers in the IPv6 PIM-SM domain.
Follow these steps to configure the IPv6 SSM group range:
To do...
Enter system view
Enter IPv6 PIM view
Configure the IPv6 SSM group
range
CAUTION:
Be sure to configure the same IPv6 SSM group range on all routers in the entire domain. Otherwise,
•
IPv6 multicast data cannot be delivered through the IPv6 SSM model.
When a member of an IPv6 multicast group in the IPv6 SSM group range sends an MLDv1 report
•
message, the device does not trigger a (*, G) join.
Configuring IPv6 PIM common features
NOTE:
In IPv6 PIM view, the configuration is effective on all interfaces. In interface view, the configuration is
•
effective on the current interface only.
If the same function or parameter is configured in both IPv6 PIM view and interface view, the
•
configuration made in interface view has preference over the configuration made in PIM view,
regardless of the configuration sequence.
