What Is RADLAN-PIM-BSR-MIB?

RADLAN-PIM-BSR-MIB is a vendor-specific private MIB from RADLAN/Marvell that configures PIM Bootstrap Router (BSR) functionality, the mechanism PIM-Sparse Mode uses to dynamically discover and distribute Rendezvous Point (RP) information across a multicast domain. It exposes configuration and administrative-state objects controlling how a device participates in BSR candidate-RP and candidate-BSR election. Its relevance to monitoring is protocol/software status: an operator can check whether BSR rows are administratively enabled and, by extension, whether the device is correctly participating in RP discovery for IP multicast. It builds on and depends on the standard PIM multicast routing framework (and implicitly the standard PIM-MIB) for its multicast concepts. It is typically deployed on Marvell/RADLAN-based Layer 3 switches or routers that run PIM-SM multicast routing and need dynamic RP discovery, where RADLAN-PIM-BSR-MIB SNMP monitoring confirms candidate-BSR and candidate-RP participation is enabled as intended.

IPNetwork Monitor allows you to monitor SNMP objects defined in RADLAN-PIM-BSR-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Marvell (formerly RADLAN) Layer 3 switches/routers

Monitoring Examples

No specific object or table names were captured for this module beyond a generic row administrative-state description, so an administrator would generally check the BSR-related row status/administrative-state objects to confirm candidate-BSR or candidate-RP configuration is enabled as intended on the device.

What Can Be Monitored

BSR row administrative state
candidate-RP/candidate-BSR configuration status

How to Use in IPNetwork Monitor

Example using rlPimBsrCandidateRPAdvTimer OID:

Select a Marvell (formerly RADLAN) Layer 3 switches/router (PIM Bootstrap Router) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type rlPimBsrCandidateRPAdvTimer into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The time remaining before the local router next sends a Candidate-RP-Advertisement to the elected BSR. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a TimeTicks-type OID, Value bounds is the most useful condition here — trigger an alert if the value stays unexpectedly high or low relative to what you'd expect for this timer, since that can indicate a stuck or stale state. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
rlPimBsrCandidateRPTable	1.3.6.1.4.1.89.220		not-accessible	The (conceptual) table listing the IP multicast group prefixes for which the local router is to advertise itself as a Candidate-RP.
rlPimBsrCandidateRPEntry	1.3.6.1.4.1.89.220.1		not-accessible	An entry (conceptual row) in the rlPimBsrCandidateRPTable.
IPt rlPimBsrCandidateRPAddressType	1.3.6.1.4.1.89.220.1.1	InetAddressType	not-accessible	The Inet address type of the Candidate-RP.
IP rlPimBsrCandidateRPAddress	1.3.6.1.4.1.89.220.1.2	InetAddress	not-accessible	The (unicast) address that will be advertised as a Candidate-RP. The InetAddressType is given by the rlPimBsrCandidateRPAddressType object. If this is not an address on the local router, DC-PIM will not advertise it as an C-RP address.
STR rlPimBsrCandidateRPGroupPrefixList	1.3.6.1.4.1.89.220.1.3	DisplayString	read-create	Identifies a standard access list containing the set of IP multicast group prefixes for which the local router will advertise itself as a Candidate-RP with the given RP address. If there is any rule in the list with aallStdAccessListIncluded set to 'false', DC-PIM does not advertise this RP address as a Candidate-RP. Otherwise DC-PIM advertises the RP address as a Candidate-RP for every IP multicast group prefix corresponding to a rule in the access list with row status 'active' and admin status 'up'. rlPimBsrCandidateRPGroupPrefixList defaults to an empty string, which indicates that no access list has yet been specified. rlPimBsrCandidateRPStatus can only be set to 'active' if a non-empty string has been specified for rlPimBsrCandidateRPGroupPrefixList.
T/F rlPimBsrCandidateRPBidir	1.3.6.1.4.1.89.220.1.5	TruthValue	read-create	If this object is set to TRUE, this group range is advertised with this RP as a BIDIR-PIM group range. If it is set to FALSE, it is advertised as a PIM-SM group range. DC-PIM only supports the value FALSE for this object.
TIK rlPimBsrCandidateRPAdvTimerEx	1.3.6.1.4.1.89.220.1.6	TimeTicks	read-only	The time remaining before the local router next sends a Candidate-RP-Advertisement to the elected BSR. This will be zero if the C-RP is shutting down or any of the following conditions are true: - the entity is not active - the row is inactive - the group prefix list is invalid - the configured C-RP address is not local.
U32 rlPimBsrCandidateRPPriority	1.3.6.1.4.1.89.220.1.7	Unsigned32	read-create	The priority for this Candidate RP advertised in Candidate-RP-Advertisements. Numerically higher values for this object indicate lower priorities, with the value zero denoting the highest priority.
U32 rlPimBsrCandidateRPAdvInterval	1.3.6.1.4.1.89.220.1.8	Unsigned32	read-create	A Candidate RP generates Candidate-RP-Advertisements periodically. This object represents the time interval in seconds between two consecutive advertisements.
U32 rlPimBsrCandidateRPHoldtime	1.3.6.1.4.1.89.220.1.9	Unsigned32	read-create	Holdtime for this Candidate RP. The amount of time (in seconds) this Candidate-RP entry is valid.
ROW rlPimBsrCandidateRPStatus	1.3.6.1.4.1.89.220.1.10	RowStatus	read-create	The status of this row, by which new entries may be created, or old entries deleted from this table. All writable objects in this entry can be modified when the status of this entry is active(1).
