## Symptoms

- * The original Single Management Object (SMO) went down due to a physical link failure (for example, a cable was accidentally disconnected).
* After restoring the link, when the original SMO recovers and becomes active again, Border Gateway Protocol (BGP) sessions fail to establish.
* BGP sessions alternate between active and connect states for 10-15 minutes before stabilizing.

## Cause

The original SMO did not synchronize BGP session state with the new SMO during failover. As a result, stale entries remained in the connection table, causing session establishment delays after recovery.

## Solution

This problem was fixed. The fix is included in:

* [Jumbo Hotfix Accumulator for R82](https://sc1.checkpoint.com/documents/Jumbo_HFA/R82/Default.htm) starting from Take 103
* [Jumbo Hotfix Accumulator for R81.20](https://sc1.checkpoint.com/documents/Jumbo_HFA/R81.20/Default.htm) starting from Take 158
