## Symptoms

- * Dynamic Routing (e.g., OSPF) might be disrupted in cluster on Gaia OS during the installation of a hotfix:

  * Cluster member, on which the hotfix is being installed still tries to peer with its neighbors.
  * Cluster member, on which the hotfix is being installed is still shown as "master" in the output of "show cluster state" command in "iclid" shell
* Stopping the RouteD daemon manually (with Expert command "*tellpm process:routed*") before the installation of a hotfix prevents this disruption / traffic outage of Dynamic Routing.

## Cause

Routing Option "Wait for Clustering" is disabled in Gaia OS on cluster members.
