Description: Manages IP unicast routing configuration, static routes, and route redistribution on Bay Networks Rapid-City series switches.

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 RC-IP-ROUTING-MIB?

RC-IP-ROUTING-MIB is a Bay Networks/Nortel enterprise MIB for the Accelar (Rapid-City) family of Layer 3 switches, covering IP unicast routing configuration such as static routes and route redistribution between routing protocols. The data it exposes is almost entirely configuration state -- per-protocol redistribution enable flags, metric types, and explicit metric values for RIP-to-OSPF, OSPF-to-RIP, direct-to-OSPF, and static-to-OSPF redistribution -- rather than raw traffic counters. Its value for monitoring is chiefly a software/protocol-status one: polling objects like rcIpRoutingRedistributeRipToOspfEnable tells an operator whether a redistribution feature is currently active, letting them confirm the switch's routing software is behaving as provisioned rather than tracking hardware health directly. It builds on and complements the standard IETF OSPF and RIP MIBs (and the base ipRouteTable), since it only governs how routes are exchanged between those protocols rather than redefining routing itself. It is typically deployed on Bay Networks/Nortel Accelar switches acting as core or distribution-layer Layer 3 devices in enterprise campus networks. Engineers can download the RC-IP-ROUTING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RC-IP-ROUTING-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.

Monitoring Examples

An administrator troubleshooting a route leak between OSPF and RIP domains would poll rcIpRoutingRedistributeOspfToRipEnable and rcIpRoutingRedistributeOspfToRipExplicitMetric to confirm whether redistribution is turned on and what metric is being injected. Similarly, checking rcIpRoutingRedistributeDirectToOspfMethod and rcIpRoutingRedistributeDirectToOspfExternalMetricType reveals how directly connected subnets are being advertised into OSPF as external routes. An unexpected enable flag or metric mismatch here would explain routing loops or suboptimal path selection observed elsewhere in the network.

What Can Be Monitored

RIP-to-OSPF redistribution status
OSPF-to-RIP redistribution status
direct route redistribution method
static route redistribution status
redistribution metric type and value

How to Use in IPNetwork Monitor

Example using rcIpStaticRouteTableSize OID:

Select a Bay Networks/Nortel Accelar (Rapid-City) Layer 3 switch (static routes/redistribution configuration) 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 rcIpStaticRouteTableSize into the Find box to locate it in the OID tree, then select it and click OK. It reports size of Ip Static Route Table. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the value drifts significantly from its normal baseline, since an unexpected change often points to a real underlying issue. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
IP rcIpInterVrfStaticRouteDest	1.3.6.1.4.1.2272.1.8.103.2.1.2	IpAddress	not-accessible	The destination IP address of this route. An entry with a value of 0.0.0.0 is considered a default route. Multiple routes to a single destination can appear in the table, but access to such multiple entries is dependent on the table- access mechanisms defined by the network management protocol in use.
T/F rcIpInterVrfStaticRouteEnable	1.3.6.1.4.1.2272.1.8.103.2.1.8	TruthValue	read-create	Used to enable/disable this entry.
rcIpInterVrfStaticRouteEntry	1.3.6.1.4.1.2272.1.8.103.2.1		not-accessible	A static route to a particular destination.
NUM rcIpInterVrfStaticRouteIfIndex	1.3.6.1.4.1.2272.1.8.103.2.1.6	InterfaceIndex	read-only	The index value which uniquely identifies the local interface through which the next hop of this route should be reached. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
T/F rcIpInterVrfStaticRouteLocalNextHop	1.3.6.1.4.1.2272.1.8.103.2.1.11	TruthValue	read-create	Used to enable/disable this entry. True indicate that the static route becomes active only if switch has a local route to the network. False indicates that the static route becomes active if switch has a local route or dynamic route.
IP rcIpInterVrfStaticRouteMask	1.3.6.1.4.1.2272.1.8.103.2.1.3	IpAddress	not-accessible	Indicate the mask to be logical-ANDed with the destination address before being compared to the value in the rcIpRouteDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value of the rcIpRouteMask by determining whether the value of the correspondent rcIpRouteDest field belong to a class-A, B, or C network, and then using one of: mask network 255.0.0.0 class-A 255.255.0.0 class-B 255.255.255.0 class-C If the value of the rcIpRouteDest is 0.0.0.0 (a default route), then the mask value is also 0.0.0.0. It should be noted that all IP routing subsystems implicitly use this mechanism.
I32 rcIpInterVrfStaticRouteMetric	1.3.6.1.4.1.2272.1.8.103.2.1.5	Integer32	read-create	The primary routing metric for this route. The semantics of this metric are determined by the routing-protocol specified in the route's rcIpRouteProto value. If this metric is not used, its value should be set to -1.
IP rcIpInterVrfStaticRouteNextHop	1.3.6.1.4.1.2272.1.8.103.2.1.4	IpAddress	not-accessible	The IP address of the next hop of this route. (In the case of a route bound to an interface which is realized via a broadcast media, the value of this field is the agent's IP address on that interface).

OID rcIpInterVrfStaticRouteOwnerVrfId	1.3.6.1.4.1.2272.1.8.103.2.1.1	VrfIdentifier	not-accessible	Owner VRF id of the static route
I32 rcIpInterVrfStaticRoutePreference	1.3.6.1.4.1.2272.1.8.103.2.1.7	Integer32	read-create	Used to indicate the route preference of this entry. If there are more than one route that can be used to forward IP traffic, the route that has a highest preference will be used instead of a lower preference one. The higher the number, the higher the preference.

It should be noted that all IP routing subsystems implicitly use this mechanism.
