Impact on the System

Traffic forwarded along the LSP will be interrupted.

Possible Causes

Cause 1: Other.

Cause 4: The out interface of the RSVP LSP ingress is down.

Cause 5: The resource of RSVP LSP is preempted.

Cause 6: RSVP message timeout.

Cause 7: RSVP neighbor lost.

Cause 8: BYPASS is down or by pass is unbinded.

Cause 100: The alarm was cleared.

Procedure

1. Check causes for each sub-LSP that went Down.

Locate the cause, and repair the sub-LSP. If the fault is rectified, go to Step 3.
If the fault persists and no cause is located, go to Step 2.

2. Collect log information and configuration information, and then contact technical support personnel.

3. End.
