- RFC 1490 netgraph node type
node type performs protocol encapsulation, de-encapsulation, and
multiplexing according to RFC 1490 (which has since been updated by RFC 2427).
This particular type of encapsulation is often used on top of frame relay
hook is used to transmit and receive encapsulated frames.
On the other side of the node, the
hooks are used to transmit and receive raw IP frames and PPP frames,
PPP frames are transmitted and received according to
RFC 1973; in particular, frames appearing on the
hook begin with the PPP protocol number.
hook can be used to transmit and receive Ethernet frames (without a
checksum) in RFC 1490s bridging format.
hook is connected to the
hook of an
This node type supports the following hooks:
Connects to the RFC 1490 peer entity.
Transmits and receives bridged raw Ethernet frames, without a checksum.
Transmits and receives raw IP frames.
Transmits and receives PPP frames.
This node type supports the generic control messages, plus the following:
This command sets encapsulation method for the node.
The desired method must be passed as a string message argument,
and must be one of the following supported encapsulation modes:
IP packets are sent using simple RFC1490/2427 encapsulation.
IP packets are sent inside SNAP frames.
Also conforms to RFC1490/2427.
IP packets are sent and received using proprietary Cisco encapsulation
This command returns current encapsulation method on the node.
This node shuts down upon receipt of a
control message, or when all hooks have been disconnected.
