Hi Eric_Chen ,

I am planning to migrate the infrastructure part from haproxy LB to F5 LB (VE / BM).  I read your article, but unable to completely understand it.  I could not configure LB using FAST template, but based on the configuration in this file https://github.com/chen23/openshift-4-3/blob/master/fast/openshift/2_infrastructure.yaml from your repository, configured the LB manually.  Could install the masters successfully but the workers are unable to join the cluster.

I see the below errors on all worker nodes.
