9. Follow steps in Bug-Fix-Steps
10. service zookeeper start on all contrail controllers
11. service supervisor-database start on all contrail controllers
12. service supervisor-config start on all contrail controllers
13. Verify gc_grace_seconds is correct using below (replace database-ip):
cat << EOF | cassandra-cli -h <database-ip> | sed -n -e  '/config_db_uuid/,/Keyspace:/p' -e '/svc_monitor_keyspace/,/Keyspace:/p' -e '/to_bgp_keyspace/,/Keyspace:/p' | grep -B4 'GC grace seconds'
show keyspaces;
EOF
14. service supervisor-analytics start
15. service supervisor-webui start
15. service supervisor-control start
16.. Using UI (Config Page) edit Global ASN, Add MX and control-node BGP routers, Add Virtual Routers
