Multicast PIM-SM

Protocol Independent Multicast - Sparse Mode (PIM-SM or PIM) provides multicast and IGMP features to RouterOS.

PIM features:

  • Manage rendezvous points
  • Multicast routing information base management
  • Distributing multicast over network

route pim

You can set settings that enable shortest-path-tree mode for multicast on RouterOS

  • switch-to-spt-bytes (0..4294967295) :

Sets after what amount of bytes pim will switch to shortest-path-tree, thus avoiding unneeded data transmissions

  • switch-to-spt-interval (time interval in seconds) :

Sets after what amount of time in seconds pim will switch to shortest-path-tree, thus avoiding unneeded data transmissions

rp

Rendezvous point configuration. Rendezvous point (RP) is a distribution point for multicast group, source provides its data to it, and if there are any subscribers, then RP will provide data to client. Note, that RP will always receive data stream if that exists.

  • comment (text) : add comment to static RP entry
  • copy-from (number) : creates another RP just like one you pointed to with number you used.
  • disabled (yes, no) : used to change status of RP entry effectively disabling or enabling it.
  • group (IP address or ip address with subnet mask) : sets what group this RP will be assigned to. Values accepted are class D ip addresses with mask, thus effectively marking multiple groups to this RP entry e.g. 224.10.10.0/24 will add 256 groups starting with 224.10.10.0 till 224.10.10.255.
  • hash-mask-length () :
  • priority () :
  • address (ip address) : at what address you have to look for RP for multicast group specified in group field. If group is set to one of routers interfaces, it should be reachable through whole multicast network, if it not, you will have to set up rules in MRIB (multicast routing information base).
