The following example displays sample output from the show bgp af-group command using the
configuration keyword. This example shows from where each configuration item was inherited. The
default-originate command was configured directly on this address family group (indicated by [ ]). The
remove-private-as command was inherited from address family group GROUP_2, which in turn
inherited from address family group GROUP_3:
RP/0/RP0/CPU0:router# show bgp af-group GROUP_1 configuration
af-group GROUP_1 address-family ipv4 unicast
capability orf prefix-list both [a:GROUP_2]
default-originate []
maximum-prefix 2500 75 warning-only []
route-policy POLICY_1 in [a:GROUP_2 a:GROUP_3]
remove-private-AS [a:GROUP_2 a:GROUP_3]
send-community-ebgp [a:GROUP_2]
send-extended-community-ebgp [a:GROUP_2]
The following example displays sample output from the show bgp af-group command using the users
keyword:
RP/0/RP0/CPU0:router# show bgp af-group GROUP_2 users
IPv4 Unicast: a:GROUP_1
The following example displays sample output from the show bgp af-group command using the
inheritance keyword. This shows that the specified address family group GROUP_1 directly uses the
GROUP_2 address family group, which in turn uses the GROUP_3 address family group:
RP/0/RP0/CPU0:router# show bgp af-group GROUP_1 inheritance
IPv4 Unicast: a:GROUP_2 a:GROUP_3
show bgp session-group
Use the show bgp session-group command to display session groups:
• Use the configuration keyword to display the effective configuration for the session group,
including any settings that have been inherited from session groups used by this session group.
• Use the inheritance keyword to display the session groups from which this session group is capable
of inheriting configuration.
• Use the users keyword to display the session groups, neighbor groups, and neighbors that inherit
configuration from this session group.
The output from the show bgp session-group command is based on the following session group
configuration:
RP/0/RP0/CPU0:router(config)# router bgp 113
RP/0/RP0/CPU0:router(config-bgp)# session-group GROUP_1
RP/0/RP0/CPU0:router(config-bgp-sngrp)# use session-group GROUP_2
RP/0/RP0/CPU0:router(config-bgp-sngrp)# update-source Loopback 0
RP/0/RP0/CPU0:router(config-bgp-sngrp)# exit
RP/0/RP0/CPU0:router(config-bgp)# session-group GROUP_2
RP/0/RP0/CPU0:router(config-bgp-sngrp)# use session-group GROUP_3
RP/0/RP0/CPU0:router(config-bgp-sngrp)# ebgp-multihop 2
RP/0/RP0/CPU0:router(config-bgp-sngrp)# exit
RP/0/RP0/CPU0:router(config-bgp)# session-group GROUP_3
RP/0/RP0/CPU0:router(config-bgp-sngrp)# dmz-link-bandwidth
