SQLite, MySQL, MariaDB, PostgreSQL database backups fail in pure IPv6 network configuration

In an IPv6 environment when multiple IP addresses are configured for the client, the client tries to connect to NetBackup Flex Scale using an IP address that is chosen at random. If the IP address is not recognized as a trusted client, the backup job fails. (4031494)

Workaround:

On the client, disable route discovery for the ethernet interface. Use the netsh command to set the routediscovery parameter to disabled.
