What Is CISCOSB-Redistribute?

CISCOSB-Redistribute is a private Cisco Small Business MIB governing route redistribution between routing protocols (e.g., static, connected, RIP, OSPF, BGP) on SMB routing devices. It exposes configuration objects describing which source protocol's routes are redistributed into which destination protocol, along with matching route-map, AS number, and metric-handling parameters. Its role in monitoring is chiefly software/configuration status: confirming that redistribution rules are correctly defined (rlRedistSrcProtocol into rlRedistDstProtocol) with the intended metric type and value, since a missing or misconfigured redistribution entry can silently black-hole routes between protocol domains. It depends conceptually on the routing protocol identifiers and process IDs used by Cisco's broader routing MIB family (e.g., matching OSPF/RIP process IDs). It is typically deployed on Cisco Small Business routers running multiple routing protocols that need controlled route exchange between domains. Network engineers evaluating or troubleshooting this functionality can download the CISCOSB-Redistribute file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCOSB-Redistribute. 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.

Monitoring Examples

An operator would inspect rlRedistTable/rlRedistEntry to verify rlRedistSrcProtocol and rlRedistDstProtocol pairs match intended redistribution (e.g., static into OSPF), and check rlRedistMetricValue/rlRedistMetricType to confirm the injected routes carry the expected cost. If rlRedistRoutMapName references a route-map that no longer exists or rlRedistMetricTransparent is set unexpectedly, routes may be redistributed with the wrong metric or filtered out entirely, causing reachability gaps. rlRedistAsNumber and rlRedistDstProcessId/rlRedistSrcProcessId help confirm redistribution is scoped to the correct BGP AS or IGP process instance.

OIDs

OID symbolic	OID numeric	Type	Access	Description
rlRedistribute	1.3.6.1.4.1.9.6.1.101.26.27
rlRedistTable	1.3.6.1.4.1.9.6.1.101.26.27.1		not-accessible	Using a routing protocol to advertise routes that are learned by some other means, such as by another routing protocol, static routes, or directly connected routes, is called redistribution. This table is used to configure under which conditions will redistribution occur and which actions (if any) should be done on redistributed route.
rlRedistEntry	1.3.6.1.4.1.9.6.1.101.26.27.1.1		not-accessible	.
RLR rlRedistDstProtocol	1.3.6.1.4.1.9.6.1.101.26.27.1.1.1	RlRedistDstProtocol	not-accessible	The protocol to which the routes are exported to
RLR rlRedistSrcProtocol	1.3.6.1.4.1.9.6.1.101.26.27.1.1.2	RlRedistSrcProtocol	not-accessible	The protocol from which the routes are imported from
INT rlRedistDstProcessId	1.3.6.1.4.1.9.6.1.101.26.27.1.1.3	INTEGER	not-accessible	Parameter semantic differs according to rlRedistDstProtocol. in OSPF this is an appropriate OSPF process ID to which routes are to be redistributed
INT rlRedistSrcProcessId	1.3.6.1.4.1.9.6.1.101.26.27.1.1.4	INTEGER	not-accessible	Parameter semantic differs according to rlRedistSrcProtocol. in BGP and EIGRP keyword, this is an autonomous system number, in range 1 to 65535.. in OSPF, this is an appropriate OSPF process ID from which routes are to be redistributed. 0 means no process ID
RLR rlRedistMatchType	1.3.6.1.4.1.9.6.1.101.26.27.1.1.5	RlRedistMatchType	not-accessible	Applicable only when rlRedistSrcProtocol is OSPF defines the criteria by which OSPF routes are redistributed into other routing domains. It can be one of the following: rlRedistMatchTypeInternal - Routes that are internal to a specific autonomous system. rlRedistMatchTypeExternalTwo - Routes that are external to the autonomous system, but are imported into OSPF as Type 2 external route. rlRedistMatchTypeExternalOne - Routes that are external to the autonomous system, but are imported into OSPF as Type 1 external route.
STR rlRedistRoutMapName	1.3.6.1.4.1.9.6.1.101.26.27.1.1.6	DisplayString	not-accessible	Specifies the route map that should be interrogated to filter the importation of routes from this source routing protocol to the current routing protocol. If not specified, all routes are redistributed. If this keyword is specified, but no route map tags are listed, no routes will be imported.
INT rlRedistAsNumber	1.3.6.1.4.1.9.6.1.101.26.27.1.1.7	INTEGER	read-write	Autonomous system number for the redistributed route. Number in range from 1 to 65535. 0 means no AS number defined
T/F rlRedistMetricTransparent	1.3.6.1.4.1.9.6.1.101.26.27.1.1.8	TruthValue	read-write	Redistribute routes without changing the metric
INT rlRedistMetricValue	1.3.6.1.4.1.9.6.1.101.26.27.1.1.9	INTEGER	read-write	When redistributing from one OSPF process to another OSPF process on the same router, the metric will be carried through from one process to the other if no metric value is specified. When redistributing other processes to an OSPF process, the default metric is 20 when no metric value is specified.
RLR rlRedistMetricType	1.3.6.1.4.1.9.6.1.101.26.27.1.1.10	RlRedistMetricType	read-write	Parameter semantic differs according to rlRedistSrcProtocol. In OSPF specifies the external link type associated with the default route advertised into the OSPF routing domain. It can be one of two values: 1 - Type 1 external route 2 - Type 2 external route
T/F rlRedistSubnets	1.3.6.1.4.1.9.6.1.101.26.27.1.1.11	TruthValue	read-write	For redistributing routes into OSPF, the scope of redistribution for the specified protocol
T/F rlRedistOnlyNSSA	1.3.6.1.4.1.9.6.1.101.26.27.1.1.12	TruthValue	read-write	Sets the nssa-only attribute for all routes redistributed into OSPF.
ROW rlRedistRowStatus	1.3.6.1.4.1.9.6.1.101.26.27.1.1.13	RowStatus	read-create	Row Status
