Hello Wai,

EXAMPLES
-------------

     The following commands will set up Ethernet interfaces fxp0 to deliver
     packets alternating over the physical interfaces corresponding to net-
     working interfaces fxp0 through fxp3:

       # Plumb nodes together
       ngctl mkpeer fxp0: one2many upper one
       ngctl connect fxp0: fxp0:upper lower many0
       ngctl connect fxp1: fxp0:upper lower many1
       ngctl connect fxp2: fxp0:upper lower many2
       ngctl connect fxp3: fxp0:upper lower many3
       # Allow fxp1 through fxp3 to xmit/recv fxp0 frames
       ngctl msg fxp1: setpromisc 1
       ngctl msg fxp3: setpromisc 1
       ngctl msg fxp2: setpromisc 1
       ngctl msg fxp1: setautosrc 0
       ngctl msg fxp3: setautosrc 0
       ngctl msg fxp2: setautosrc 0
       # Configure all four links as up
       ngctl msg fxp0:upper \
         setconfig "{ xmitAlg=1 failAlg=1 enabledLinks={ 1 1 1 1 } }"
       # Bring up interface
       ifconfig fxp0 192.168.1.1 netmask 0xfffffffc

     With a similar setup on a peer machine (using the address 192.168.1.2),
a
     point-to-point Ethernet connection with four times normal bandwidth is
     achieved.

Later.
