When an IPsec Security Association (SA) does not exist on a remote IPsec peer, the BIG-IP system might be sent an INVALID-SPI notification, but might not delete the SA. The IPsec tunnel might not be renegotiated until the deleted SAs on the BIG-IP system are removed manually or age out.
IPsec tunnel appears to be up but suffers a connectivity loss until the SPIs are manually deleted or age out.
-- The BIG-IP system and remote peer communicate over a lossy network. -- The remote peer prematurely deletes an IPsec SA.
Manually delete the SA.
The system now correctly handles these conditions so the issue no longer occurs.
