Description: Juniper Networks MIB for managing virtual router instances, routing contexts, and associated interfaces on Juniper E-series platforms.

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 Juniper-ROUTER-MIB?

Juniper-ROUTER-MIB is a Juniper Networks vendor-specific module for the E-series (ERX/E120/E320) platform, managing the creation, deletion, and administrative state of logical/virtual routers (VRs and VRFs) that run within a physical chassis. It exposes summary counts of configured virtual router instances alongside a per-router table giving each virtual router's name, context, VRF association, and row (creation/administrative) status. Its monitoring role is chiefly configuration/operational-status tracking for virtualization on the box: the summary counts let an operator confirm the expected number of virtual routers exist, while juniRouterRowStatus on each entry confirms a given virtual router is active rather than stuck mid-creation or being torn down. It underlies protocol- and interface-level MIBs scoped per virtual router context, since routing protocols and interfaces on an E-series box are managed relative to the router context they belong to. It is deployed specifically on Juniper E-series edge/broadband routers used by service providers for large-scale subscriber and VRF-based routing separation. Operators managing many virtual routers often browse the Juniper-ROUTER-MIB OID subtree directly to enumerate all provisioned VR/VRF entries at once rather than polling them individually.

IPNetwork Monitor allows you to monitor SNMP objects defined in Juniper-ROUTER-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

Juniper E-series router (ERX/E120/E320)

Monitoring Examples

An operator would poll juniRouterTable/juniRouterEntry, checking juniRouterRowStatus for each juniRouterName to confirm a provisioned virtual router is fully active, and cross-check juniRouterSummaryTotalConfigured against the expected count to catch a VR that failed to instantiate. juniRouterVrf and juniRouterContextName together let an operator map a virtual router to its VRF and see which routing context downstream interface/protocol MIBs should be queried against. A sudden drop in juniRouterSummaryParentVRsConfigured could indicate an unexpected virtual router deletion affecting subscriber routing separation.

What Can Be Monitored

number of virtual routers configured
number of VRFs configured
virtual router administrative/row status
virtual router name and routing context
total configured router instance count

SNM juniRouterContextEngineID	1.3.6.1.4.1.4874.2.2.32.1.2.1.6	SnmpEngineID	read-only	The virtual router SNMP engine's administratively-unique identifier. This is used as the contextEngineId to reach the virtual router's SNMP context via the system-wide SNMP engine using SNMPv3.
OCT juniRouterContextName	1.3.6.1.4.1.4874.2.2.32.1.2.1.5	OCTET STRING	read-only	An internally derived/assigned name given to this router with a specific format: routerN where N is a decimal number (with no leading zeroes) in the range 1..16777215 corresponding to the value of the least significant 24 bits of the juniRouterIndex (the router UID). The name is unique within the context of this table.
juniRouterEntry	1.3.6.1.4.1.4874.2.2.32.1.2.1		not-accessible	Each entry in this table represents a single router. Creating and/or deleting entries in this table causes corresponding entries to be created or deleted in the juniRouterProtocolTable. Note that VRFs also appear as entries in this table and can be differentiated by the juniRouterVrf object. The juniRouterVrfTable shows the parent / child relationship between routers and VRFs present in the system.

A GET of this object returns the next available routerIndex value to be used to create an entry in the associated router table; or zero, if no valid routerIndex value is available. This object also returns a value of zero when it is the lexicographic successor of a varbind presented in an SNMP GETNEXT or GETBULK request, for which circumstance it is assumed that routerIndex allocation is unintended. Successive GETs will typically return different values, thus avoiding collisions among cooperating management clients seeking to create table entries simultaneously.
juniRouterObjects	1.3.6.1.4.1.4874.2.2.32.1
juniRouterProtocolEntry	1.3.6.1.4.1.4874.2.2.32.1.3.1		not-accessible	Each entry provides administrative control on a router protocol for the router designated by the first indice to this table. The second indice identifies the router protocol. Entries in this table are created as a side-effect of row creation in the juniRouterTable or juniRouterVrfTable.
JUN juniRouterProtocolProtocolIndex	1.3.6.1.4.1.4874.2.2.32.1.3.1.2	JuniRouterProtocolIndex	not-accessible	Identities the router protocol.
U32 juniRouterProtocolRouterIndex	1.3.6.1.4.1.4874.2.2.32.1.3.1.1	Unsigned32	not-accessible	The routerIndex of this router. This object is the same as the juniRouterIndex object defined in the juniRouterTable.
ROW juniRouterProtocolRowStatus	1.3.6.1.4.1.4874.2.2.32.1.3.1.3	RowStatus	read-write	Administrative control and status of a protocol on a router. The following values can be read from this object: active(1) - Indicates that the protocol on the designated router is created, configured, and running. notReady(3) - Indicates that the protocol requires additional configuration in a protocol specific MIB module. Examples include the BGP and OSPF protocols, which require additional configuration of protocol specific parameters such as: Autonomous System (AS) for BGP, and Process Id for OSPF. destroy(6) - The destroy(3) operation can fail if there are executing applications dependent on the protocol. If an attempt is made to destroy(6) an active(1) protocol that other applications are dependent on, the rowStatus will read destroy(6). Normally, when a row is destroyed, the agent will cleaup and remove the entry. The following values can be written to this object: active(1) - Activate protocol on the designated router. createAndGo(4) - Create protocol on designated router. The router indicated by juniRouterProtocolRouterIndex must already exist in the juniRouterTable. The value of the juniRouterProtocolProtocolIndex must be from the set of protocol values defined by the JuniRouterProtocolIndex type. destroy(6) - Destroy protocol on designated router. If the operation is successful, the agent will remove the entry. If the operation failed, the row will remain in the table with a rowStatus value of destroy(6). Conditions on destroy(6): 1) The default router can not be deleted. 2) The local router can not be deleted. A local router is defined as the router that sourced the SNMP request. Upon creation of a router in the juniRouterTable, some protocol entries will appear in this table by default, which indicates that these protocols are created by the action of creating a router. It is important to note, that this behavior may change over time by protocol type.
