    I have two nic bge0 and bge0, and I would like them
    to have the same IP address in case that my redundant
    switch stop responding. Bridge is not an option,
    I tried with netgraph but I did not succeed.
    Does anyone have some solution?

    I followed the examples from google groups and I stuck with
    duplicated packets when both ethernets are plugged and
    50% packet loss when one ethernet is unplugged, damn !!#@!#@!$%^@$#@

    here is my config

    rc.conf
    ifconfig_bge0="1.2.3.4 netmask 255.255.0.0 media 100baseTX mediaopt
    full-duplex"
    ifconfig_bge1="media 100baseTX mediaopt full-duplex"

    and /usr/local/etc/rc.d/bonding.sh

     #!/bin/sh
    ifconfig bge1 up
    kldload /boot/kernel/ng_ether.ko
    kldload /boot/kernel/ng_one2many.ko
    ngctl mkpeer bge0: one2many upper one
    ngctl connect bge0: bge0:upper lower many0
    ngctl connect bge1: bge0:upper lower many1
    ngctl msg bge1: setpromisc 1
    ngctl msg bge1: setautosrc 0
    ngctl msg bge0:upper setconfig "{xmitAlg=1 failAlg=1 enabledLinks =[ 1
    1 ] }"

    manual for this sucks
