Chapter 1 What’s New for FortiOS 5.0 : New features in FortiOS 5.0 Patch 2 : IPv6 PIM sparse mode multicast routing
  
IPv6 PIM sparse mode multicast routing
FortiOS supports PIM sparse mode multicast routing for IPv6 multicast (multicast6) traffic and is compliant with RFC 4601: Protocol Independent Multicast - Sparse Mode (PIM-SM). You can use the following command to configure IPv6 PIM sparse multicast routing.
config router multicast6
set multicast-routing {enable | disable}
config interface
edit <interface-name>
set hello-interval <1-65535 seconds>
set hello-holdtime <1-65535 seconds>
end
config pim-sm-global
config rp-address
edit <index>
set ipv6-address <ipv6-address>
end
The following diagnose commands for IPv6 PIM sparse mode are also available:
diagnose ipv6 multicast status
diagnose ipv6 multicast vif
diagnose ipv6 multicast mroute
