vrSresRtEntriesUsed
Virtual Router Sres Rt Entries Used
This attribute specifies the total number of SourceRouteEndStation routing table entries. The value is limited by the attribute routeTableNumEntries, which is a provisionable attribute. If the value is consistently approaching the value of routeTableNumEntries, it is advisable to increase the value provisioned for routeTableNumEntries. It indicates a potential shortage of routing table entries in the future.
