Enable PIM Enable or disable Protocol Independent Multicast (PIM).In a
PIM enabled environment, each subnet must have a
designated PIM router (PIM DR). Many routers today supports
taking the role as the PIM DR and for those cases the PIM
should not be enabled in the Sencore unit.
For routers that cannot act as PIM DR the PIM should be
enabled in the Sencore unit. In this case the Sencore takes
over the role as the subnet PIM DR. The Sencore PIM DR is
signaling its own multicasts only; hence other sources on the
same network will be time out and become unavailable.
This feature requires the output redundancy license.
RP Point RP Point – Rendezvous point
Enable Mute On Error Check to enable or disable Mute on Error
Switching delay(s) Number of seconds to wait before the output is switched to the
backup path, in case of errors.
10.3.2.2 Stream specific settings
When the global redundancy attributes are defined, output redundancy must be enabled for all
outgoing streams. When enabled the output redundancy will monitor the stream status and if
any errors perform the appropriate action.
Depending on the configuration, the results of an alarm trigger would be:
•
Send an OSPF to the next hop router and announces that the source is no longer
present.
o
Note that the multicast will still be transmitted.
o
Note that in a multicast system it is the source that is disabled, which means if
multiple outputs are given the same source address then both/all streams
will be regarded stopped by the router.
•
Mute the output, ie 0 bitrate, when ’Mute On Error’ is enabled
