#!/bin/sh
# script to set up a frame relay link on the sr card.
# The dlci used is selected below. The default is 16
# $FreeBSD$
CARD=sr0
DLCI=16
# create a frame_relay type node and attach it to the sync port.
ngctl mkpeer ${CARD}: frame_relay rawdata downstream
# Attach the dlci output of the (de)multiplexor to a new
# Link management protocol node.
ngctl mkpeer ${CARD}:rawdata lmi dlci0 auto0
# Also attach dlci 1023, as it needs both to try auto-configuring.
# The Link management protocol is now alive and probing..
ngctl connect ${CARD}:rawdata ${CARD}:rawdata.dlci0 dlci1023 auto1023
# Attach the DLCI(channel) the Telco has assigned you to
# a node to handle whatever protocol encapsulation your peer
# is using. In this case RFC1490 encapsulation.
ngctl mkpeer ${CARD}:rawdata rfc1490 dlci${DLCI} downstream
# Attach the ip (inet) protocol output of the protocol mux to the ip (inet)
# input of a netgraph "interface" node (ifconfig should show it as "ng0").
#if interface ng0 needs to be created use a mkpeer command.. e.g.
ngctl mkpeer ${CARD}:rawdata.dlci${DLCI} iface inet inet
# if ng0 already exists, use a CONNECT command instead of a mkpeer. e.g.
# ngctl connect ${CARD}:rawdata.dlci${DLCI} ng0: inet inet
# Then use ifconfig on interface ng0 as usual
# A variant on this whole set might use the 'name' command to make it more
# readable. But it doesn't work if you have multiple lines or dlcis
# e.g.
# ngctl mkpeer ${CARD}: frame_relay rawdata downstream
# ngctl name ${CARD}:rawdata mux
# ngctl mkpeer mux: lmi dlci0 auto0
# ngctl name mux:dlci0 lmi
# ngctl connect mux: lmi: dlci1023 auto1023
# ngctl mkpeer mux: rfc1490 dlci${DLCI} downstream
# ngctl mux:dlci${DLCI} protomux
# ngctl mkpeer protomux: iface inet inet
