Description: Alcatel OmniSwitch Distance Vector Multicast Routing Protocol MIB for multicast routing table and interface management.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ALCATEL-IND1-DVMRP-MIB?

ALCATEL-IND1-DVMRP-MIB is an Alcatel enterprise MIB for the OmniSwitch product line's Coronado Layer 3 Hardware Routing Engine, implementing management of the Distance Vector Multicast Routing Protocol (DVMRP). It exposes multicast routing configuration and operational data, including per-interface DVMRP administrative status, tunnel interfaces, and protocol timers governing route reporting, flash updates, neighbor probing, pruning, and grafting. Its monitoring value centers on multicast routing protocol health and configuration correctness: administrators can verify DVMRP is administratively enabled where expected, confirm neighbor and route timeout/hold-down timers match design intent, and detect misconfiguration that could cause multicast route flapping or pruning storms, rather than exposing classic hardware sensors. It is a vendor extension layered on top of the general concepts of the IETF DVMRP multicast routing model. It is deployed on Alcatel (later Alcatel-Lucent) OmniSwitch Layer 3 switches used as multicast-capable routing engines in enterprise or campus backbone networks. Network engineers evaluating or troubleshooting this functionality can download the ALCATEL-IND1-DVMRP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ALCATEL-IND1-DVMRP-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

Alcatel-Lucent Enterprise (ALE) OmniSwitch Layer 3 switches (Coronado hardware routing engine)

Monitoring Examples

An administrator would check alaDvmrpAdminStatus per routing interface to confirm DVMRP is enabled where multicast routing is expected, and review alaDvmrpTunnelXIfTable entries to validate configured DVMRP tunnel interfaces to remote multicast islands. Inspecting alaDvmrpNeighborTimeout, alaDvmrpRouteExpirationTimeout, and alaDvmrpPruneLifetime against the vendor defaults can reveal a misconfigured timer causing premature neighbor loss or excessive prune/graft churn, both of which manifest as intermittent multicast traffic loss.

What Can Be Monitored

DVMRP admin status per interface
DVMRP tunnel interfaces
neighbor timeout
route expiration/hold-down timers
prune/graft retransmission intervals

alaDvmrpGlobalConfig	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1
INT alaDvmrpAdminStatus	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.1	INTEGER	read-write	Administratively enables/disables the DVMRP protocol on this router.
I32 alaDvmrpRouteReportInterval	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.2	Integer32	read-write	The Route Report Interval determines how often a router will send its complete routing tables to neighboring routers running DVMRP.
I32 alaDvmrpFlashUpdateInterval	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.3	Integer32	read-write	The minimum Flash Update Interval defines how often routing table change messages are sent to neighboring DVMRP routers. Since these messages are sent between the transmission of complete routing tables, the flash update interval value must be shorter than that of the route report interval.
I32 alaDvmrpNeighborTimeout	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.4	Integer32	read-write	The Neighbor Timeout value specifies how long, without any activity from a neighboring DVMRP router, the router will wait before assuming that the inactive router is down.
I32 alaDvmrpRouteExpirationTimeout	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.5	Integer32	read-write	The Route Expiration Timeout value specifies how long the router will wait before aging out a route. When this value expires, the route is advertised as inactive until either it's activity resumes or it is deleted.
I32 alaDvmrpRouteHoldDown	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.6	Integer32	read-write	Specifies the time during which DVMRP routes are kept in a hold-down state. A hold-down state refers to the time that a route to an inactive network continues to be advertised.
I32 alaDvmrpNeighborProbeInterval	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.7	Integer32	read-write	The Neighbor Probe Interval value specifies how often probes will be transmitted to those interfaces with attached DVMRP neighbors.
I32 alaDvmrpPruneLifetime	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.8	Integer32	read-write	The Prune Lifetime value defines the value whereby a source-rooted multicast tree will be pruned.
I32 alaDvmrpPruneRetransmission	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.9	Integer32	read-write	The Prune Packet Retransmission value is the duration of time that the router will wait, if it continues to receive unwanted multicast traffic, before retransmitting a prune message.
I32 alaDvmrpGraftRetransmission	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.10	Integer32	read-write	The Graft message Retransmission value defines the duration of time that the router will wait before retransmitting a graft message, if it has not already received an acknowledgement from its neighbor.
T/F alaDvmrpInitNbrAsSubord	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.11	TruthValue	read-write	The value true(1) indicates neighbors, on initial discovery, are considered subordinate. This means traffic may be resumed slightly quicker on network disruptions. But, if the neighbor has trouble handling huge initial blasts of traffic, it may be wise to wait until route reports have been exchanged and the neighbor has requested dependency, before forwarding traffic.
INT alaDvmrpBfdStatus	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.12	INTEGER	read-write	Enables/Disables Bfd for DVMRP Protocol.
INT alaDvmrpBfdAllInterfaceStatus	1.3.6.1.4.1.6486.801.1.2.1.10.7.1.1.1.13	INTEGER	read-write	Enables/Disables Bfd for all DVMRP interfaces.
