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 work in the same IPv6 PIM mode.
For more information about the multicast ipv6 routing-enable command, see Network Management
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 in 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-SSM domain.
To configure the IPv6 SSM group range:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 PIM view. pim ipv6 N/A
3. Configure the IPv6 SSM group
range.
ssm-policy acl6-number
Optional.
FF3x::/32 by default, here "x"
refers to any legal group scope.
CAUTION:
•
Make sure that the same IPv6 SSM group range is configured 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.
