Simplifying Access Lists with Object Grouping

Adding a Network Object Group

To add or change a network object group, follow these steps. After you add the group, you can add more
objects as required by following this procedure again for the same group name and specifying additional
objects. You do not need to reenter existing objects; the commands you already set remain in place unless
you remove them with the no form of the command.
A network object group supports IPv4 and IPv6 addresses, depending on the type of access list. For more
