That's actually beyond that document scope.

Anyway, /usr/share/initscripts-*/sysconfig.txt has the info you need to 
integrate those comments on RHEL. Like, for the ip rule commands:

/etc/sysconfig/network-scripts/rule-<interface-name>
/etc/sysconfig/network-scripts/rule6-<interface-name>

   Contains lines that specify additional routing rules that should be added
   when the associated interface is brought up.

   Each non-comment line is used directly as an argument to "/sbin/ip 
rule add"
   or "/sbin/ip -6 rule add" for rule6 files.


YMMV if you want to use NetworkManager/firewalld, of course.
