rtg Dpn Delay Metric Cut Off

This attribute specifies the delay metric value beyond which a destination RID should be considered unreachable. That is, if a delay metric to a RID is equal to or greater than this value then the RID is considered to be unreachable in the delay class of service. Lowering this value has the effect of speeding up the detection of the loss of reachability to a RID. It also reduces the amount of Routing Table Update (RTU) traffic generated in this scenario. Care must be taken to ensure that the value chosen is big enough for the longest delay path in the network. This attribute is optional; a default of 128 is used when it is not set. It is recommended that all nodes in the network be provisioned with the same cut off value.
