Usage guidelines
Service loopback groups must work with other features, such as GRE, and a service loopback group can
be used by multiple features.
You must create a service loopback group first before you can use it with a feature.
Only one service loopback group is allowed for a service type. You cannot change the service type of a
service loopback group.
To ensure correct traffic handling, do not delete a service loopback group that is being used.
