Thanks! If I only have 2 interfaces, Do I need to assign IP address for
fxp0 and fxp1 first then assign the 3rd IP on aggregated fxp1 (eg:
64.123.123.123 for fxp0, 65.123.123.123 for fxp1, and 64.123.123.124 for
aggregated fxp0)?
BTW, let me try to make condition a bit more clear:
|--- www.xxx.yyy.zzz (ISP A) -----|
| |
|---------| |
| FreeBSD | |
| 4.2R | |--Internet
|---------| |
| |
|--- aaa.bbb.ccc.ddd (ISP B) -----|
Will ng_one2many work for such condition?
best wishes,

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.
