본딩을 일일히 구성하는게 귀찮아진 나머지 스크립트를 짜려다, 혹시나 해서 검색해보니 좋은 스크립트가 있어서 소개!
출처는 맨 아래 적어놓았으며, 약간의 수정을 했다^^

# This script creates bonding interfaces on RHEL 5.
#
# The first and second parameters are used to specify the enslaved interfaces.
# The third parameter is used to describe the name of the bonding interface.
# The network configuration is collected from the first device.
# After running the script please verify the/etc/modprobe.conf file as well as
# all/etc/sysconfig/network-scripts/ifcfg* files!
