46 .In netgraph/rfc1490/ng_rfc1490.h
50 node type performs protocol encapsulation, de-encapsulation, and
51 multiplexing according to RFC 1490 (which has since been updated by RFC 2427).
52 This particular type of encapsulation is often used on top of frame relay
57 hook is used to transmit and receive encapsulated frames. On the other
62 hooks are used to transmit and receive raw IP frames and PPP frames,
63 respectively. PPP frames are transmitted and received according to
64 RFC 1973; in particular, frames appearing on the
66 hook begin with the PPP protocol number.
70 hook is connected to the
76 This node type supports the following hooks:
77 .Bl -tag -width foobarbazum
79 Connects to the RFC 1490 peer entity.
81 Transmits and receives raw IP frames.
83 Transmits and receives PPP frames.
86 This node type only supports the generic control messages.
88 This node shuts down upon receipt of a
90 control message, or when all hooks have been disconnected.
