[lustre-discuss] luster 2.10.3 lnetctl configurations not persisting through reboot

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
              0: ib0
              send_count: 2958318
              recv_count: 2948077
              drop_count: 0
              peer_timeout: 180
              peer_credits: 8
              peer_buffer_credits: 0
              credits: 256
          lnd tunables:
              peercredits_hiw: 4
              map_on_demand: 256
              concurrent_sends: 8
              fmr_pool_size: 512
              fmr_flush_trigger: 384
              fmr_cache: 1
              ntx: 512
              conns_per_peer: 1
          tcp bonding: 0
          dev cpt: 0
          CPT: "[0,1]"

Is this expected behavior?
