NAME

     ng_hub - packet distribution netgraph node type

SYNOPSIS

     #include <netgraph/ng_hub.h>

DESCRIPTION

     The hub node type provides a simple mechanism for distributing packets
     over several links.  Packets received on any of the hooks are forwarded
     out the other hooks.  Packets are not altered in any way.

HOOKS

     A hub node accepts any request to connect, regardless of the hook name,
     as long as the name is unique.

CONTROL MESSAGES

     This node type supports only the generic control messages.

SHUTDOWN

     This node shuts down upon receipt of a NGM_SHUTDOWN control message, or
     when all hooks have been disconnected.

SEE ALSO

     netgraph(4), ng_bridge(4), ng_ether(4), ng_one2many(4), ngctl(8),
     nghook(8)

HISTORY

     The ng_hub node type appeared in FreeBSD 5.3.
