Configuring the source interface enables you to use a more stable address (such as the loopback interface
address) as the source address of relayed messages.
The DHCPv6 relay source interface can be configured globally, per interface, or both. When both the global
and interface levels are configured, the interface-level configuration overrides the global configuration.
This command does not require a license.
