  Note: On R80.40 run:
  ``# for i in `vsx stat -v | egrep -v "Not Applicable|SIC"| grep Trust| awk '{print $1}'`; do vsenv $i; ifconfig | grep wrp; done; vsenv 0``

  <br />

* No routes relevant for WRP interfaces are seen on VS's on VSX with Kernel 3.10  

  This can be checked with the command:  
  ``
  # for i in `cpstat vsx -f stat | grep "Virtual System" | cut -f 2 -d "|"`; do vsenv $i; route -n; done; vsenv 0``

  Note: On R80.40 run:

  ``# for i in `vsx stat -v | egrep -v "Not Applicable|SIC"| grep Trust| awk '{print $1}'`; do vsenv $i; route -n; done; vsenv 0``
