which BGP configuration group allows you to define address-family independent commands and address-family dependent commands for each address family?

For address family-independent configuration, the following applies:
* Neighbors can inherit from session groups and neighbor groups.
* Neighbor groups can inherit from session groups and other neighbor groups.
* Session groups can inherit from other session groups.
For address family-dependent configurations, the following applies:
* Address family groups can inherit from other address family groups.
