Configuring an IPv6 multicast source policy

This feature enables the device to filter IPv6 multicast data by using an ACL that specifies the IPv6
multicast sources and the optional groups. It filters not only IPv6 multicast data packets but also IPv6
PIM register messages with IPv6 multicast data encapsulated. This also reduces the IPv6 multicast
traffic on the network.
To configure an IPv6 multicast source policy:

Enter IPv6 PIM view.

source policy.

Configuring an IPv6 PIM hello policy

This feature enables the device to filter IPv6 PIM hello messages by using an ACL that specifies the
packet source addresses. It is used to guard against IPv6 PIM message attacks and to establish
correct IPv6 PIM neighboring relationships.
If hello messages of an existing IPv6 PIM neighbor are filtered out by the policy, the neighbor is
automatically removed when its aging timer expires.

policy.

Configuring IPv6 PIM hello message options

In either an IPv6 PIM-DM domain or an IPv6 PIM-SM domain, hello messages exchanged among
routers contain the following configurable options:
•
DR_Priority (for IPv6 PIM-SM only)—Priority for DR election. The device with the highest
priority wins the DR election. You can configure this option for all the routers in a shared-media
LAN that directly connects to the IPv6 multicast source or the receivers.
•
Holdtime—IPv6 PIM neighbor lifetime. If a router receives no hello message from a neighbor
when the neighbor lifetime expires, it regards the neighbor failed or unreachable.
•
LAN_Prune_Delay—Delay of pruning a downstream interface on a shared-media LAN. This
option has LAN delay, override interval, and neighbor tracking support (the capability to disable
join message suppression).
The LAN delay defines the IPv6 PIM message propagation delay. The override interval defines
a time period for a downstream router to override a prune message. If the propagation delay or
