    I configured an lnet router today with luster 2.10.3 as the lustre software.  I then connfigured the lnet router using the following lnetctl commands
    lnetctl lnet configure
    lnetctl net add --net o2ib0 --if ib1
    lnetctl net add --net o2ib1 --if ib0
    lnetctl set routing 1
    When I rebooted the router the configuration didn't stick.  Is there a way to make this persist through a reboot?
    I also notices that when I do an export of the lnetctl configuration it contains
        - net type: o2ib1
          local NI(s):
            - nid: <ip of a compute node>@o2ib1
              status: up

    Is this expected behavior?
