 **NOTES:**
     - higher number of pg-l2 interfaces causes problems => only 15 pg-l2 \
     interfaces in 5 bridge domains are tested
-    - more then 1 host per pg-l2 interface in configuration with 15 l2-pg \
-     interfaces leads to problems too
+    - jumbo packets in configuration with 14 l2-pg interfaces leads to \
+    problems too
 
 **config 1**
     - add 15 pg-l2 interfaces
