A configuration with a DNS Express Zone with an underscore in the name does not load, even though the gtm global-settings general domain-name-check is set to any of allow-underscore, svn-compatible, or none.
Cannot load the LTM configuration when restarting BIG-IP system when DNS Express Zones that have an underscore character in the name.
-- Configuration setting gtm global-settings general domain-name-check is set to any of allow-underscore, svn-compatible, or none. -- DNS Express Zone exists with an underscore in the name.
Force the GTM configuration to load by sequentially running the following commands: tmsh load sys config gtm-only. tmsh load sys config.
All FQDNs may now contain underscore character. The BIG-IP system now correctly load configurations that contain DNS Express Zones with underscores in the name.
