4**NOTES:**
5 - higher number of pg-ip4 interfaces causes problems => only 15 pg-ip4 \
6 interfaces in 5 VRFs are tested
7 - jumbo packets in configuration with 15 pg-ip4 interfaces leads to \
8 problems too
Jane546d3b2016-12-08 13:10:03 +01009
10**config 1**
11 - add 15 pg-ip4 interfaces
12 - configure 5 hosts per pg-ip4 interface

20 - check VRF data by parsing output of ip_fib_dump API command
