Multicast (PIM-SIM)

Protocol Independent Multicast (PIM) is a protocol for routing IP packets efficiently to multicast groups that may span the internet. PIM provides dynamic multicast support on the device. With dynamic multicast support, a host can join or leave a multicast group dynamically, and you don't need to add or delete multicast routing entries on the device manually.

Note The device supports PIM version2 and PIM-SM mode with Rendezvous Point (RP) selection method as BSR (Bootstrap Router)

PIM-SM configuration

Enable PIM
Turn on PIM to provide dynamic multicast support on the device.
PIM-enabled interface

Select the physical interfaces on which the PIM service needs to be turned on. You must select at least one interface.

Only IPv4 bound interfaces can be selected.

RED and GRE interfaces are supported.

Alias, PPPoE, and cellular WAN interfaces are not supported.

RP settings
Turn this on to configure static RP or candidate RP.
Table 1. Static RP

RIP IP

Specify a unicast IP address for static RP. RPs can be added or deleted. Maximum eight RP IP addresses per RP are allowed.

Multicast group

Specify multicast group IP address or network address separated by a comma that will be served by the given RP. Maximum eight multicast group addresses per RP are allowed. Use * in the multicast group list to serve all the multicast groups by the defined RP.

Table 2. Candidate RP

Candidate RP IP

Select interface IP that will be used as RP IP, if the router is selected as candidate RP.

Multicast group list

Specify multicast group IP address or network address separated by a comma that will be served by given RP. A maximum of eight multicast groups IP or network addresses are allowed. Use * in the multicast group list to serve all the multicast groups by the selected RP.

Candidate RP priority

Specify the priority of the PIM router in the RP election process. Default: 1. Acceptable range: 1 to 255.

Timer

Specify time in seconds after which at every specified time, RP candidate messages are generated. Default: 60 seconds. Acceptable range: 30 to 180 seconds.
