Static Route Object Tracking using IP SLA
This feature is used to track the state of an object for reachability using IP SLA. A client process such as Virtual Router Redundancy Protocol (VRRP), or RIB, can register its interest in tracking objects and then be notified when a state change occurs.
IP SLA (Service-Level Assurance) is a performance measurement protocol. The protocol is used to Analyze IP Service Levels for IP applications and services. IP SLAs uses active traffic-monitoring technology to monitor continuous traffic on the network.
IP SLA uses Internet Control Message Protocol (ICMP) pings to identify a link failure and notifies to the clients that are registered for tracking.
The Object Tracking feature provides complete separation between the objects to be tracked and the action to be taken by a client when a tracked object state changes. Thus, several clients such as VRRP, or RIB can register their interest with the tracking process, track the same object, and each take different action when the object changes. The Tracking feature will be present in OAMD.
Each tracked object is identified by a unique number that is specified in the tracking command. Client processes use this number to track a specific object.
The tracking process processes events from the tracked objects and notes any change of value. The changes in the tracked object are communicated to interested client processes, either immediately or after a specified delay. The object values are reported as either up or down.
