Configuration prerequisites
Before you configure IPv6 PIM common features, complete the following tasks:
• Enable IPv6 forwarding and configure any IPv6 unicast routing protocol so that all devices in the
domain are interoperable at the network layer.
• Configure IPv6 PIM-DM, IPv6 PIM-SM or IPv6 PIM-SSM.
• Determine the IPv6 ACL for filtering IPv6 multicast data.
• Determine the IPv6 ACL that defines a legal source address range for hello messages.
• Determine the priority for DR election—global value/interface level value.
• Determine the IPv6 PIM neighbor timeout time—global value/interface value.
• Determine the prune message delay—global value/interface level value.
• Determine the prune override interval—global value/interface level value.
• Determine the prune delay.
• Determine the hello interval—global value/interface level value.
• Determine the maximum delay between hello message—interface level value.
• Determine the assert timeout time—global value/interface value.
• Determine the join/prune interval—global value/interface level value.
• Determine the join/prune timeout—global value/interface value.
• Determine the IPv6 multicast source lifetime.
• Determine the maximum size of join/prune messages.
• Determine the maximum number of (S, G) entries in a join/prune message.
Configuring an IPv6 multicast data filter
In either an IPv6 PIM-DM domain or IPv6 PIM-SM domain, routers can check passing-by IPv6 multicast
data based on the configured filtering rules and determine whether to continue forwarding the IPv6
multicast data. In other words, IPv6 PIM routers can act as IPv6 multicast data filters. These filters can
help implement traffic control and also control the information available to downstream receivers to
enhance data security.
