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 is 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.
CAUTION:
•
Make sure 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.
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.
Configuring IPv6 PIM common features
IPv6 PIM common feature configuration task list
Task Remarks
Configuring an IPv6 multicast data filter Optional.
Configuring a hello message filter Optional.
Configuring IPv6 PIM hello options Optional.
Configuring the prune delay Optional.
Configuring IPv6 PIM common timers Optional.
Configuring join/prune message sizes Optional.
Configuring BFD for IPv6 PIM Optional.
For the configuration tasks in this section:
• In IPv6 PIM view, the configuration takes effect on all interfaces. In interface view, the configuration
takes effect on only the current interface.
• If the same function or parameter is configured in both IPv6 PIM view and interface view, the
configuration in interface view has preference over the configuration in PIM view, regardless of the
configuration sequence.
