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

[John Mok]

Dear Roman,

Thank you for your information. I have succeeded to setup the frame 
relay using netgraph. However, I failed to get the interface ng0 up :-

#ifconfig ng0 1.2.3.4 255.255.255.0 up
ifconfig: interface ng0 does not exist

Please help to advise how I could make the interface ng0 appears.

Thank you,   John Mok
