Viewing Inherited Configurations - Cisco NCS 6000 Series Configuration Manual

Implementing BGP
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
• Use the inheritance keyword to display the session groups, neighbor groups, and address family groups
The show bgp neighbors command examples that follow are based on this sample configuration:
RP/0/RP0/CPU0:router(config)# router bgp 142
RP/0/RP0/CPU0:router(config-bgp)# af-group GROUP_3 address-family ipv4 unicast
