692 CHAPTER 46: IPV6 PIM CONFIGURATION
Configuration
Prerequisites
Before configuring IPv6 PIM common information, complete the following tasks:
■ Configure any IPv6 unicast routing protocol so that all devices in the domain
are interoperable at the network layer.
■ Configure IPv6 PIM-DM (or IPv6 PIM-SM)
Before configuring IPv6 PIM common information, prepare the following data:
■ An IPv6 ACL rule as IPv6 multicast data filter
■ Priority for DR election (global value/interface level value)
■ IPv6 PIM neighbor timeout time (global value/interface value)
■ Prune delay (global value/interface level value)
■ Prune override interval (global value/interface level value)
■ Hello interval (global value/interface level value)
■ Maximum delay between hello message (interface level value)
■ Assert timeout time (global value/interface value)
■ Join/prune interval (global value/interface level value)
■ Join/prune timeout (global value/interface value)
■ IPv6 multicast source lifetime
■ Maximum size of join/prune messages
■ Maximum number of (S, G) entries in a join/prune message
Configuring an IPv6 PIM
filter
No matter in an IPv6 PIM-DM domain or an IPv6 PIM-SM domain, devices 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 devices can act as IPv6 multicast data filters. These filters can help
implement traffic control on one hand, and control the information available to
downstream receivers to enhance data security on the other hand.
Follow these steps to configure an IPv6 PIM filter:
