Session Preempted Event

 

LSP Event

Session preempted

Sample Output 1

Sample Output 2

Meaning

This LSP event indicates that the LSP session was taken over. Sample Output 1 shows the IP address (10.1.13.2) included with the event, indicating the IP address of the router that sent the message. Sample Output 2 does not include an IP address, indicating that the message originated on the ingress router.

Cause

The state of the network might have changed, as shown in Sample Output 1, or an LSP with a higher priority might be using the bandwidth of the LSP.

Action

Refer to the events preceding this event in the history log for more information on what might have caused the preemption. For example, in line 62, the CSPF failed message may indicate that you specified a disable constrained-path (no-cspf) LSP and an explicit route address that is strict and not directly connected. Additionally, the egress router might have changed its configuration, making the destination address unreachable.
