Task Remarks
3043H
Enabling IPv6 PIM-SM Required.
3044H
Configuring the IPv6 SSM group range Optional.
3045H
Configuring common IPv6 PIM features Optional.
995BConfiguration 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.
996BEnabling IPv6 PIM-SM
The implementation of the SSM model is 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.
IMPORTANT:
A
ll the interfaces on a device must be enabled with the same IPv6 PIM mode.
To enable IPv6 PIM-SSM:

997BConfiguring the IPv6 SSM group range
Whether the IPv6 PIM-SSM model or the IPv6 PIM-SM model delivers the information from an IPv6
multicast source depends on whether the group address in the (S, G) packet that the receivers request
falls into the IPv6 SSM group range. All IPv6 PIM-SM-enabled interfaces assume the IPv6 PIM-SSM model
for IPv6 multicast groups within this address range.
When you configure the IPv6 SSM group range, follow these guidelines:
• 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.
