Tunnel flapping frequently occurs due to keepalive detection failures in an SD-WAN scenario.

Trouble Ticket Number

DTS2024102516258

Symptom

Tunnel flapping frequently occurs due to keepalive detection failures in an SD-WAN scenario.

Condition

The quality of the intermediate network is poor in an SD-WAN scenario.

Impact

Frequent tunnel flapping affects service experience.

Severity

Minor

Root Cause

Keepalive detection packets are continuously discarded on the network, causing frequent tunnel flapping.

Solution

1. Keepalive detection enhancement is enabled by default to improve the accuracy of keepalive detection.

2. The keepalive detection process is optimized.

Solution Impact

None
