Viewing Inherited Configurations - Cisco ASR 9000 Series Routing Configuration Manual

BGP Configuration
For Address Family: IPv4 Unicast
4 Otherwise, the default value is used. In the example that follows, neighbor 10.0.101.5 has the minimum
time between advertisement runs set to 30 seconds (default) because the neighbor is not configured to use
the neighbor configuration or the neighbor group configuration:
RP/0/RSP0/CPU0:router(config)# router bgp 140
RP/0/RSP0/CPU0:router(config-bgp)# neighbor-group AS_1
RP/0/RSP0/CPU0:router(config-bgp-nbrgrp)# remote-as 1
RP/0/RSP0/CPU0:router(config-bgp-nbrgrp)# exit
RP/0/RSP0/CPU0:router(config-bgp)# neighbor-group adv_15
RP/0/RSP0/CPU0:router(config-bgp-nbrgrp)# remote-as 10
RP/0/RSP0/CPU0:router(config-bgp-nbrgrp)# advertisement-interval 15
RP/0/RSP0/CPU0:router(config-bgp-nbrgrp)# exit
RP/0/RSP0/CPU0:router(config-bgp)# neighbor 10.0.101.5
RP/0/RSP0/CPU0:router(config-bgp-nbr)# use neighbor-group AS_1
RP/0/RSP0/CPU0:router(config-bgp-nbr)# exit
RP/0/RSP0/CPU0:router(config-bgp)# neighbor 10.0.101.10
RP/0/RSP0/CPU0:router(config-bgp-nbr)# use neighbor-group adv_15
The following output from the show bgp neighbors command shows that the advertisement interval used
is 30 seconds:
RP/0/RSP0/CPU0:router# show bgp neighbors 10.0.101.5
BGP neighbor is 10.0.101.5, remote AS 1, local AS 140, external link
Remote router ID 0.0.0.0
For Address Family: IPv4 Unicast
Connections established 0; dropped 0
The inheritance rules used when groups are inheriting configuration from other groups are the same as the
rules given for neighbors inheriting from groups.
