HOWTO connect MCI using Netgraph + Frame Relay with Digi SYNC/570i

[John Mok]

After issuing the following commands :-

#ngctl mkpeer sync_ar0: frame_relay rawdata downstream
#ngctl mkpeer sync_ar0:rawdata lmi dlci0 ansi
#ngctl mkpeer sync_ar0:rawdata rfc1490 dlci16 rfc1490
#ngctl mkpeer sync_ar0:rawdata dlci16 rl0 inet inet
#ifconfig ng0 1.2.3.4 5.6.7.8
ifconfig: interface ng0 does not exist

The command ifconfig shows :-

rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    options=8<VLAN_MTU>
    inet6 fe80::207:40ff:fe09:f09%rl0 prefixlen 64 scopeid 0x1
    inet 192.168.255.254 netmask 0xffffff00 broadcast 192.168.255.255
    ether 00:07:40:09:0f:09
    media: Ethernet autoselect (none)
    status: no carrier
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    options=9<RXCSUM,VLAN_MTU>
    inet6 fe80::201:3ff:fec1:9c58%xl0 prefixlen 64 scopeid 0x2
    ether 00:01:03:c1:9c:58
    media: Ethernet autoselect (100baseTX <full-duplex>)
    status: active
xl1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    options=9<RXCSUM,VLAN_MTU>
    inet6 fe80::201:3ff:fe34:61af%xl1 prefixlen 64 scopeid 0x3
    inet 192.168.16.254 netmask 0xffffff00 broadcast 192.168.16.255
    ether 00:01:03:34:61:af
    media: Ethernet autoselect (100baseTX <full-duplex>)
    status: active
plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
    inet6 ::1 prefixlen 128
    inet6 fe80::1%lo0 prefixlen 64 scopeid 0x5
    inet 127.0.0.1 netmask 0xff000000

and the command "ngctl list" shows :-

There are 4 total nodes:
  Name: ngctl811        Type: socket          ID: 00000011   Num hooks: 0
  Name: <unnamed>       Type: frame_relay     ID: 00000004   Num hooks: 1
  Name: sync_ar1        Type: sync_ar         ID: 00000002   Num hooks: 0
  Name: sync_ar0        Type: sync_ar         ID: 00000001   Num hooks: 1

Would it be the problem that I test it with cable disconnected from the 
modem (i.e.CSU/DSU)?

Thanks a lot.
