PIM-SM routing
The PIM-SM routing examples in the "Networking handbook" are not very clear. Why is there added an access-list, which is never used int the config? Has anyone a really working PIM-routing example from practice?
Thanks.

On Fortigate, to enable multicast routing, you will need to:
1.
config system settings
set multicast-forward enable
end
2.
config router multicast
set multicast-routing enable
end
3.
config router multicast
config pim-sm-global
config rp-address
...
set ip-address x.x.x.x
4.
config router multicast
config interface
edit xx
set pim-mode sparse-mode
end
5.
config firewall multicast-policy
Here are some trouble shooting commands:
get router info multicast pim sparse-mode table x.x.x.x
get router info multicast pim sparse-mode neighbour
diagnose ip multicast mroute
get router info multicast igmp groups
get router info multicast pim sparse-mode interface
get router info multicast pim sparse-mode rp-mapping
get router info multicast pim sparse-mode bsr-info
diagnose sys mcast-session list
Follow up with this thread with any question please. Thanks!

http://help.fortinet.com/...%20a%20static%20RP.htm
But I know, that an RP can be restricted to specific Multicastgroups via an ACL. I found another configuration Guide with the following configuration example:
The ACL defines a filter to the multicastgroup 233.254.200.0
config router access-list edit "Source-RP" config rule edit 1 set prefix 233.254.200.0 255.255.255.0 set exact-match disable next
In another step, the ACL is bound to teh RP:
config router multicast config interface edit "internal" set pim-mode sparse-mode config igmp set version 2 end next edit "external" set pim-mode sparse-mode config igmp set version 2 end next end set multicast-routing enable config pim-sm-global config rp-address edit 1 set ip-address 169.254.100.1 set group "Source-RP" next
