[Susmit]

Can you try this?
nfdc route add /ndn ether://[01:00:5e:00:17:aa] local dev://eth1

Hi all,



I have NFD and ndn-cxx 5.1 installed on a few GENI machines. They are fresh
Ubuntu 16.04.1 LTS machines. I want to configure NDN over Ethernet
multicast, but encountered issues.



Here’s my `nfdc face list` showing the two Ethernet faces (256 and 257)
that were automatically created.

faceid=1 remote=internal:// local=internal:// counters={in={0i 60d 0n
38130B} out={116i 0d 0n 8956B}} flags={local permanent point-to-point
local-fields}

faceid=254 remote=contentstore:// local=contentstore:// counters={in={0i 0d
0n 0B} out={0i 0d 0n 0B}} flags={local permanent point-to-point}

faceid=255 remote=null:// local=null:// counters={in={0i 0d 0n 0B} out={0i
0d 0n 0B}} flags={local permanent point-to-point}

faceid=256 remote=ether://[01:00:5e:00:17:aa] local=dev://eth0
counters={in={0i 0d 0n 0B} out={0i 0d 0n 0B}} flags={non-local permanent
multi-access}

faceid=257 remote=ether://[01:00:5e:00:17:aa] local=dev://eth1
counters={in={0i 0d 0n 0B} out={0i 0d 0n 0B}} flags={non-local permanent
multi-access}

faceid=258 remote=fd://29 local=unix:///run/nfd.sock counters={in={105i 3d
0n 7303B} out={3i 45d 0n 27457B}} flags={local on-demand point-to-point
local-fields}

faceid=259 remote=udp4://224.0.23.170:56363 local=udp4://172.17.1.5:56363
counters={in={0i 0d 0n 0B} out={0i 0d 0n 0B}} flags={non-local permanent
multi-access}

faceid=260 remote=udp4://224.0.23.170:56363 local=udp4://10.10.4.2:56363
counters={in={0i 0d 0n 0B} out={0i 0d 0n 0B}} flags={non-local permanent
multi-access}

faceid=274 remote=fd://34 local=unix:///run/nfd.sock counters={in={1i 0d 0n
46B} out={0i 0d 0n 0B}} flags={local on-demand point-to-point}



And here’s my `nfdc route list`

1503006545.761235 INFO: [UnixStreamTransport]
[id=0,local=unix:///run/nfd.sock,remote=fd://34]

1503006545.761277 INFO: [FaceTable] Added face id=275 remote=fd://34

1503006545.771459 INFO: [Transport]

I tried to add a face using the command `nfdc route add /ndn
ether://[01:00:5e:00:17:aa]`, but since I have two Ethernet faces it threw
an error:

Multiple faces match specified remote FaceUri. Re-run the command with a
FaceId: 256 (local=dev://eth0), 257 (local=dev://eth1)



I re-ran the command appending the network device according to the above
message:

`nfdc route add /ndn ether://[01:00:5e:00:17:aa] local=dev://eth1`



But got the error:

cannot parse 'local' as an argument name



Also tried just the network device, as described here
<https://redmine.named-data.net/projects/nfd/wiki/FaceMgmt#Ethernet>, but
got the same message.



What’s the correct syntax?



Thank you,

Thiago Teixeira
