Fixed In:

Opened: Jun 25, 2020
Severity: 4-Minor

Symptoms

After failover, the active BIG-IP system fails to respond to DPD requests from some of its eNB neighbors, which results in deletion of IKE tunnel peer as well as the BIG-IP system.

Impact

Since BIG-IP systems do not respond to DPD requests, eNB deletes the IKE tunnel after a few retries.

Conditions

-- The BIG-IP is configured with more than 300 IKE/IPsec tunnels. -- The BIG-IP system fails over.

Workaround

None.

Fix Information
