**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
