Configuration Prerequisites; Enabling Ipv6 Pim-Sm; Configuring The Ipv6 Ssm Group Range - HP FlexFabric 5950 series Configuration Manual

Configuration prerequisites

Before you configure IPv6 PIM-SSM, configure an IPv6 unicast IPv6 routing protocol so that all
devices in the domain can interoperate at the network layer.

Enabling IPv6 PIM-SM

Before you configure IPv6 PIM-SSM, you must enable IPv6 PIM-SM, because the implementation of
the IPv6 SSM model is based on subsets of IPv6 PIM-SM.
When you deploy an IPv6 PIM-SSM domain, enable IPv6 PIM-SM on non-border interfaces of the
routers.
IMPORTANT:
All the interfaces on a device must be enabled with the same IPv6 PIM mode.
To enable IPv6 PIM-SM:
Step
1. Enter system view.
2. Enable IP multicast routing,
and enter MRIB view.
3. Return to system view.
4. Enter interface view.
5. Enable IPv6 PIM-SM.

Configuring the IPv6 SSM group range

When an IPv6 PIM-SM enabled interface receives an IPv6 multicast packet, it checks whether the
IPv6 multicast group address of the packet is in the IPv6 SSM group range. If the IPv6 multicast
group address is in this range, the IPv6 PIM mode for this packet is IPv6 PIM-SSM. If the IPv6
multicast group address is not in this range, the IPv6 PIM mode is IPv6 PIM-SM.
Configuration restrictions and guidelines
When you configure the IPv6 SSM group range, follow these restrictions and guidelines:
•
Configure the same IPv6 SSM group range on all routers in the entire IPv6 PIM-SM domain.
Otherwise, IPv6 multicast information 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.
Configuration procedure
To configure an IPv6 SSM group range:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
