Associating Track With Pbr - HP 5130 EI Series Configuration Manual

The next hop of the static route is not reachable.
The configured static route is invalid.
If the track entry is in NotReady state, the following conditions exist:
•
The accessibility of the next hop of the static route is unknown.
The static route is valid.
When you associate Track with static routing, follow these restrictions and guidelines:
• You can associate a nonexistent track entry with a static route. The association takes effect only after
you use the track command to create the track entry.
If a static route needs route recursion, the associated track entry must monitor the next hop of the
•
recursive route instead of that of the static route. Otherwise, a valid route might be considered
invalid.
To associate Track with static routing:
Step
1. Enter system view.
2. Associate the static
route with a track
entry to check the
accessibility of the
next hop.

Associating Track with PBR

PBR specifies the next hop for packets that match specific ACLs. For more information about PBR, see
Layer 3—IP Routing Configuration Guide.
PBR cannot detect the availability of any action taken on packets. When an action is not available,
packets processed by the action might be discarded. For example, if the next hop specified for PBR fails,
PBR cannot sense the failure and continues to forward the matching packets to the next hop.
This problem can be solved by associating Track with PBR. The association improves the flexibility of the
PBR application and enables PBR to sense topology changes.
After you associate a track entry with an apply clause, the detection module associated with the track
entry sends the detection result of the availability of the tracked object.
The Positive state of the track entry shows that the object is available, and the apply clause is valid.
