An updated initscripts package that fixes a bug is now available for Red Hat Enterprise Linux 6.
The initscripts package contains system scripts to boot your system, change runlevels, activate and deactivate most network interfaces, and shut the system down cleanly.
Prior to this update, users were unable to set the VLAN tag to 0 when creating a logical network. With this update, the ifup script has been updated to permit this value, and the VLAN identification number can now be set to 0 as expected.
All users are advised to upgrade to this updated package, which fixes this bug.
