Not sure how the syntax should look like...

Test 1
Add a unicast route at one end. Should create the corresponding face on the other end.

Host 1:
nfdc face create ether://[a0:36:9f:36:e1:42] local dev://enp68s0f0.801
nfdc route add /test 266

Host 2:
[root@atmos-lbl ~]# nfd-status|grep test
/test nexthops={faceid=280 (cost=0)}
/test routes={nexthop=280 origin=app cost=0 flags=child-inherit expires=never}

catchunks/putchunks work too.

Test 2:

One producer, two consumers. Works as expected.

On producer: face: /test nexthops={faceid=274 (cost=0)}
Two Incoming faces:

1498270069.251630 DEBUG: [Forwarder] onIncomingInterest face=265 interest=/test/%FD%00%00%01%5C%D7%DAo%F5/%00B

Trace log is here:

Test 3:

Host 1: Select an interface

faceid=257 remote=ether://[01:00:5e:00:17:aa] local=dev://enp68s0f1.801 counters={in={5i 0d 0n 195B} out={0i 1d 0n 84B}} flags={non-local permanent multi-access}

Host 2:

faceid=256 remote=ether://[01:00:5e:00:17:aa] local=dev://enp68s0f0.801 counters={in={0i 1d 0n 84B} out={5i 0d 0n 195B}} flags={non-local permanent multi-access}

Add a route (/test) on the multicast face.

/test nexthops={faceid=256 (cost=0)}
The other end receives the packets on face 257.

Now, add a unicast route on host2. Now, host 2 has two routes.
/test nexthops={faceid=256 (cost=0), faceid=269 (cost=0)}

The first is chosen (as expected). On host1, receiving side, the multicast face is correctly chosen.
