(PIM)
Multicast Routing is a protocol used for transmitting data (in particular real time multimedia flows,
such as videoconferences or streaming video) simultaneously to different destinations.
In Imola routers there is Multicast automatic routing by using the Protocol Independent Multicast
(PIM).
In addition to static routing rules, PIM-Sparse Mode (PIM SM), PIM Source Specific Multicast (PIM
SSM) and PIM-Dense Mode (PIM DM) are supported.
For the activation the command is:
set pim on
The command:
set pim off
deactivates the PIM protocol.
The command:
set no-pim
deactivates the PIM protocol and removes it from the configuration.
PIM DENSE MODE protocol configuration
The configuration of PIM protocol in dense mode includes the following commands:
set pim mode dense
used to define the working mode.
set interface <string> enable [localpref] <int>
used to activate the service on the specified interface. It can be used for Dense mode only.
PIM SPARSE MODE protocol Configuration
The configuration of the PIM protocol in sparse mode includes the following commands:
set pim mode sparse
used to define the working mode
set pim bsr-cand-intf <val>
it enables the Candidate Bootstrap Router function on the interface. The parameter
<val>
indicates
that network interface or the IP address selected.
set pim bsr-prio <val>
it defines the priority for the role of bootstrap router. The
<val>
parameter can assume values from
0
to
255
. The higher the value, the higher the priority.
set pim rp-cand-intf <interface>
