The inheritance rules used when groups are inheriting configuration from other groups are the same as the
rules given for neighbors inheriting from groups.
Viewing Inherited Configurations
You can use the following show commands to view BGP inherited configurations:
show bgp neighbors
Use the show bgp neighbors command to display information about the BGP configuration for neighbors.
• Use the configuration keyword to display the effective configuration for the neighbor, including any
settings that have been inherited from session groups, neighbor groups, or address family groups used
by this neighbor.
• Use the inheritance keyword to display the session groups, neighbor groups, and address family groups
from which this neighbor is capable of inheriting configuration.
The show bgp neighbors command examples that follow are based on this sample configuration:
