dvmrpReachableRoutes
Module: DVMRP-MIB
OID (symbolic): DVMRP-MIB::dvmrpReachableRoutes
OID (numeric): 1.3.6.1.3.62.1.1.10
Node type: OBJECT-TYPE
Type: Gauge32
Access: read-only
Description: The number of entries in the routing table with non infinite metrics. This can be used to detect network partitions by observing the ratio of reachable routes to total routes.
What is dvmrpReachableRoutes?
The number of DVMRP routing table entries whose metric is not infinite, i.e. routes that are actually usable rather than marked unreachable. Comparing this to dvmrpNumRoutes lets an admin spot network partitions: a low reachable-to-total ratio suggests parts of the multicast topology have become isolated.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.3.62.1.1.10 snmpwalk -v2c -c public <target> DVMRP-MIB::dvmrpReachableRoutes
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.3.62.1.1.10.1 snmpget -v2c -c public <target> DVMRP-MIB::dvmrpReachableRoutes.1
