#=head2 routeop is called by makeroutes command and setuproutes postscript to
# setup a route on a node.
# The syntax is:
# routeop add/delete net mask gateway ifname
# routeop add/delete net mask gateway ifnamea #NOTE: the add/delete will be
# obsoleted, using 'replace' is recommended.
# routeop replace net mask gateway ifname #NOTE: it only works for sles so far
# net - IP of net like 192.168.1.0. The keyword
# 'default' is used to set the default route.
# mask - The length of the netmask
# gatewasy - The next hop. It could be set to "" or 0.0.0.0
# mask - The length of the netmask (CIDR) like 8,16,24
# dotted-decimal format like 255.255.0.0 is not supported.
# gateway - The next hop. It could be set to 0.0.0.0 for omitting
# ifname - The interface to route to the next hop
# example: routeop replace default 0 10.1.0.209 eth0
#=head3 example
# routeop replace default 0 10.1.0.209 eth0
# routeop replace 50.1.0.0 16 10.1.0.210 eth0
# routeop replace 60.1.1.0 24 0.0.0.0 eth0
# routeop replace 70.1.1.0 24 10.1.0.211 #NOTE: this is NOT supported for redhat
