# This directive is only relevant if you need to set up WCCP(v1)
# to some very old and end-of-life Cisco routers. In all other
# setups it must be left unset or at the default setting.
# It defines an internal version in the WCCP(v1) protocol,
# with version 4 being the officially documented protocol.
#
# According to some users, Cisco IOS 11.2 and earlier only
# support WCCP version 3. If you're using that or an earlier
# version of IOS, you may need to change this value to 3, otherwise
# do not specify this parameter.
#Default:
# wccp_version 4
