• If the detection result is not valid, the state of the track entry is NotReady. For example, the track
entry state is NotReady if its associated NQA operation does not exist.
The following detection modules can be associated with the Track module:
• NQA.
• BFD.
•
CFD.
•
Interface management.
Collaboration between the Track module and an application module
The following application modules can be associated with the Track module:
•
Static routing.
•
Policy-based routing.
• Smart Link.
Collaboration application example
The following is an example of collaboration between NQA, Track, and static routing.
Configure a static route with next hop 192.168.0.88 on the device. If the next hop is reachable, the static
route is valid. If the next hop becomes unreachable, the static route should become invalid. For this
purpose, configure collaboration between the NQA, track, and static routing modules:
1. Create an NQA operation to monitor the accessibility of IP address 192.168.0.88.
2. Create a track entry and associate it with the NQA operation. When the next hop 192.168.0.88
is reachable, the track entry is in Positive state. When the next hop becomes unreachable, the track
entry is in Negative state.
3. Associate the track entry with the static route. When the track entry turns to the Positive state, the
static route is valid. When the associated track entry turns to Negative state, the static route is
invalid.
Track configuration task list
To implement the collaboration function, establish associations between the Track module and the
detection modules, and between the Track module and the application modules.
To configure the Track module, perform the following tasks:
